DISCO search syntax manual

DISCO uses Westlaw and Lexis-style search syntax with boolean search operators. These can be used in a fieldless search or with a field such as tag(Responsive or "Further Review"). This guide explains how to search in DISCO. For a training video about DISCO's search and review features, see DISCO 101: Search & Review.

Search basics

Operators	Description	Example
`&`,`and`	Includes results with both terms	`contract & payment` `contract and payment` — Documents that contain both contract and payment
`[space]`,`or`,`\|`	Includes results with either term or field	`contract payment` `contract or payment` — Documents that contain contract or payment
`%`,`not`	Excludes term or field from results	`contract % payment` `contract not payment` — Documents that contain contract but do not contain payment
`+family`	Includes family members as search hits for the entire query or any portion of a query learn more here	`to("Jane.Smith@email.com")+family & "risk factors"` — Returns emails, and family members of those emails, sent to Jane.Smith@email.com that include the phrase “risk factors” `tag(Responsive)+family % tag(Attorney-Client)+family` — Returns documents tagged Responsive and documents whose family members are tagged Responsive, but removes documents tagged Attorney-Client and family members of documents tagged Attorney-Client.
`“ ”`	Exact phrase intended	`“contract payment”` — Documents that contain the exact phrase contract payment `“Matt.Motley@email.com”` — Documents that contain the email address Matt.Motley@email.com Be sure to include quotes when searching for an email address. *Note that not all DISCO fields are equipped for exact match phrase searches depending on the field type.
`!`	Truncation search or root expander; can be used at the beginning of a term, end of a term, or both. Also can be used to return all documents.	`contract!` — Documents that contain any term starting with contract, for example, contract, contracts, contractual, contracting, or contracted `!contract` — Documents that contain any term ending with contract, for example, subcontract `filename(!contract!)` — Documents with the term contract anywhere in the file name `!`— All documents `! % type(email)`— All documents except those of type email
`*`	Wildcard search for single character	`contract` — Searches for words that have one, but only one, character after contract,* such as contracts, but not contracted, contractual, or contract
`/n`,`w/n`	Proximity search, searching within n words, in any order DISCO also supports `/p` and `/s` shorthand. learn more here	`contract /10 payment` — Documents that contain contract within ten words of payment, where the order is irrelevant
`+n`,`w+n`	Proximity search, searching within n words in prescribed order	`contract +10 payment` — Documents that contain contract within ten words of payment, where contract must precede payment
`~`	Fuzzy or approximate word search. Fuzzy searching allows for the addition, deletion, or substitution of up to two letters in a word.	`guaranty~` — Searches for guaranty, guarantee, garanty, and similar (mis)spellings
`.`	Period in a name or email address	`Matt.Motley` — Documents that contain Matt.Motley (with the period), but not MattMotley (without the period)
`( )`	Grouping syntax	`(failure & consideration) & (contract agreement)` — Documents must contain both failure and consideration, and must also contain either contract or agreement
`sample(n, search)`	Returns n documents randomly selected from results of search. If n is less than 1, this number is treated as a percentage.	`sample(.5, contract)`; `sample(700, contract)` — Returns 50% and 700 of the search results for contract at random, respectively
`field(terms)`	Field searching (see below for standard DISCO fields)	`custodian(Holcombe)` — Documents with Holcombe in the custodian field

DISCO ignores most punctuation and non-alphanumeric characters when searching. Periods, colons, semicolons, and apostrophes within a word are not removed. As an example, periods in a name or email address are indexed and searchable. Word operators (and, or, and not) can be searched if placed in quotation marks, “contract and payment”.

Order of operations

DISCO performs a search using the following order of operations:

Term modifiers: !, *, ~
Exact phrases: “ ”
Groupings: ( )
Proximity: /n, +n
Family subsearch: +family
&, and, %, not
[space], or

Reviewing & searching document families

DISCO has two powerful features to help you navigate and search families of documents: family inclusion mode and family subsearch.

Family mode allows reviewers to review documents in the context of their entire family by including family members in the search results list.
Family subsearch is a search syntax capability allowing you to include family members as search hits. +family can be added to any valid query, or any portion of a query that would be a valid standalone query.

Document fields

Fieldless, or keyword, search includes the document text, subject lines, and authors for matters created after June 16, 2025. For matters created on or before June 16, 2025, fieldless search also includes document notes, custodians, and user defined fields.

Please see Finding Redacted Records for more metadata redaction search examples.

Custom fields

DISCO supports user defined fields created in the product, and custom fields ingested from a load file. The search syntax works similarly for both types of custom fields.

Example	Description
`Deposition(!)`	Documents with any contents in the Deposition field
`Deposition(Important)`	Documents with the word Important in the Deposition field
`"My notes"(!)`	Documents with any contents in the My notes field
`"My notes"("Review again")`	Documents with Review again in the My notes field

There are two additional searches for user defined fields.
