The most powerful capability in Gimmal Discover's eDiscovery module is its ability to search a wide variety of electronically stored information. Searches may be created and managed through the Search screen in the eDiscovery module of Discover. Each search is associated with a matter; so, to create a search, you will need to first create a matter.
You can access the Search screen in one of two ways; selecting a matter in the Matter screen and clicking the Searches button found in the More toolbar to view a list of the searches defined for the selected matter or by clicking the Search option in the left-hand pane of the eDiscovery module. Notice there is a drop-down box for matter, to see searches related to a specific matter, select it from the list or choose ‘all matter” to see a list of all searches that you have access to.
The details displayed for each of the searches are:
Name – The user-assigned name for the search
Matter – The name of the matter that the search is associated with. Click the matter name to view a few matter details
Status – information on the last time the search was performed
Collections - The number of collections that the search has been used in
Search Results - The number of results returned the last time the search was executed. Clicking this number opens the view to review the search results
Data Source - The targeted data source that this search is configured to run against
Last Update - The date that the search criteria were last updated
The Action toolbar menu has the following actions:
Add Search – Click to add a new search
Add Quick Search – for a content area that supports indexing, perform a search using that index
Copy Search – copy the parameters of an existing search to create a new version
Edit Search – Select a search and click this button to modify the search configuration. The search configuration can no longer be changed if it has been used in a collection; the Edit button will be disabled in this case.
Schedule Search - Select a search and click this button to automate the execution of the search on a schedule. There are three types of scheduling options available: a one-time schedule, a periodic schedule configuration that executes the search every x minutes, and a weekly schedule configuration which allows for the execution of the search on certain days/weeks of the month
Delete Search - Deleting a search will delete the search configuration, the details of all the times the search was executed, and all the stored result details
Start Search – Select one or more searches and click this button to initiate the search(es). This button will be disabled if the selected search is currently running
Stop Search – This button is enabled only when the selected search is in progress. Click it to initiate the cancellation of the execution. Because of the distributed nature of the search process, it may take a few minutes before the process is completely canceled at the client(s) where the search is running.
Pause Search – temporarily place an in-process search on hold
Request Logs – Obtain a copy of the logs for a search that is currently processing
The More toolbar menu has the following actions:
Search History - Select a search and click this button to view a list of each time the search has been executed

Creating a Search
Click the Create Search button to launch the wizard; the General Information wizard page is opened.
Fill in a name and a description, if necessary. From the Matter list, select the matter that this search is associated with. A matter is required to save the search. Specify an of the result options listed below, then click Next.
Recurring Search – this is a search that will be performed multiple times, this selecting this option will generate a cumulative result set of those multiple searches
Cache Results – make a local copy of any item returned as a search result. Checking this box will open another dialog where the cache location may be specified
Collect Results – makes an immediate collection of the search results, this option is used when no review of the results will be performed. Checking this box will open another dialog where the collection location may be specified
Retrieve Full Text – store an extracted copy of the text for each search result. Selecting this option will open another dialog where you may choose to return results for a sample (i.e., retrieve full text for 100 results) or all items
DeNist – automatically exclude items deemed non-discoverable by the National Institute of Standards and Technology
Process Timeout – specify a timeout period for the search. Helpful when searching desktop computers that may not be connected for an extended period
On the Data Source page, choose the source(s) you would like to target. The criteria and action options that appear in subsequent wizard pages depend on your data source choice. Discover permits the creation of an unlimited number of searches for a single matter to accommodate the searching of multiple data sources. Click Next.
On the Custodian page, click the Add Custodian button to select one or more custodians, whose data you would like to search, from the list of custodians assigned to the matter you selected on the previous screen. Click Next.
The Non-custodial Targets screen is displayed. This page displays a list of target types supported by Discover for your environment. Non-custodial targets are typically items not associated with a specific data owner (aka custodian). For example, a network file share that an entire department has access to. Select any targets in this list that you would like to include in the search. Click Next.
The Criteria page is displayed. The criteria available for messages in email-based data sources include:
Size of the Messages
Age of the Messages
Date of the Messages
Address Criteria (senders or recipients)
Addresses Criteria (domains)
Classification (Discover Classification module label)
The criteria for files include:
Size of the files
Age of files
Names of files
Classification (Discover Classification module label)
To configure a criterion, click the checkbox next to the criteria; this will expand the accordion panel so you can supply the specific parameters. You may configure multiple criteria options. Please note that if you do, all the selected criteria parameters will have to be met for an item to be included as a search result. Click Next after you have configured the necessary criteria.
The Keyword wizard page is displayed. If you wish to search on keywords, check the Use Keyword option. Select the appropriate type of keyword search you would like to perform:
Word List (Any) - Fill in a list of keywords, one per line. If an item being searched, contains any of the listed keywords, the item will be considered a hit.
Word List (All) - Fill in a list of keywords, again one per line. All the listed keywords must be found in the items being searched for the item to be considered a hit.
Search Expression - Discover keyword searching supports a wide variety of keyword expressions including Boolean, regular expressions, proximity, and more.
Simple – the search stops after finding the first matching keyword
Complete – all keyword criteria will be recorded in the search results (note, this will extend the time required to perform the search)
Exhaustive – used in conjunction with proximity search (i.e. find Term_a NEAR(5) Term_b) to apply all keyword criteria either before or after the proximity specified
Snippet Keyword Length – determines how much text around the matching search term will be returned as part of the snippet shown in the search results grid.
Mask Patterns – if the search expression uses one of the built-in Pattern(CC) or Pattern(SSN) options, mask this sensitive text in the search result to protect personally identifiable information.
Luhn Verification – when using a regular expression to identify credit card numbers, use the Luhn algorithm to help eliminate false positives.
After entering your search terms or expression, there is a Test button located on the right-hand side of the page. This button will open a logic test panel. The logic tester will validate the accuracy of your search expression and allow you to enter some sample text to help determine if the search terms are being evaluated properly. For more information on the search syntax options supported in Discover, please refer to the Keyword Search Syntax document.
Click Save to store the search configuration. Please note, searches do not start automatically. They must be selected and initiated using the ‘Start’ option found in the Action menu option or attached to a schedule for unattended initiation.
Viewing Search Results
There are several ways to view the results of an executed search. In the Search screen, you either click on the value in the Results column or select the search then click the Search Results option shown under the More button in the toolbar. To view the results of a prior execution of the search, select the search, click the Search History button in the toolbar and click on the results of the execution you would like to view.
The columns of information displayed in the Search Results screen vary depending on the data type of the target information that was searched. Filters on the left of the screen allow you to drill down on the results; click on one or more filters and click the Apply button to refresh the results list with results that match the selected filters. Click the Clear Filters button to clear all selected filters and reload the full list of search results.
Clicking the checkbox on the header line of the results table selects/deselects all the results displayed on the current page. Clicking the Select All/Clear All buttons on the toolbar will select/deselect all the results across all the pages of the results.
Discover offers a mechanism to tag results for further processing by applying text labels. For example, items may be marked with a ‘responsive’ label if they are to be included in a collection, or perhaps as privileged if you want to exclude them from additional processing. Labels are defined for each customer and are normally specific to the review process used with their organization.
To tag results, select the results then select the Assign Label option found under the Action button on the toolbar. The dialog that is opened displays a list of pre-defined labels; you could also add a label if you don't see one that meets your tagging needs. A result item can be assigned multiple tags. In addition to categorizing your search results, labels are used to target the result items that will be collected for more advanced review. See the section on Collections for more details on setting up a collection.
To clear the labels from a tagged result, select the result item(s) and click the Clear Label button from the toolbar.
