Pipeline query interface

A system for presenting filter history to a user, comprising:

• a memory;
• at least one processor coupled to the memory;
• a first display area configured to show an initial corpus of documents relevant to a litigation;
• a second display area configured to show a first modifiable query;
• a third display area configured to show a second modifiable query;
• and
• a fourth display area configured to show a named result set from the second modifiable query acting on a first result set from the first modifiable query with a name that identifies the first result set,
• wherein each element of the named result set is labeled with a respective label of the name that identifies the named result set, the respective label enabling presentation of the first and second modifiable queries in response to a user selection, and
• wherein each result set includes links to one or more documents relevant to the litigation that are stored across a plurality of clients, the tool further configured to:
• determine a change in either the first modifiable query in the first display area or the second modifiable query in the second display area, and
• automatically update the named result set, without additional user involvement, to reflect the change in either the first modifiable query or second modifiable query.

A non-transitory computer readable storage medium having a plurality of instructions stored thereon that, when executed by one or more processors, cause the one or more processors to execute a method of filtering a corpus of documents, comprising:

• identifying a corpus of documents relevant to a litigation to be filtered;
• generating a first modifiable query, wherein the first modifiable query comprises desired characteristics of the documents in the corpus;
• filtering the corpus of documents in accordance with the first modifiable query into a first result set;
• naming the first result set of the first modifiable query with a first name that identifies the first result set;
• generating a second modifiable query;
• filtering the first result set in accordance with the second modifiable query to generate a second result set based on the first modifiable query and the second modifiable query, the filtering the first result set further comprising:
• applying the second modifiable query to the first result set by using the first result set, specified by the first name that identifies the first result set, as a source of documents for the applying the second modifiable query;
• naming the second result set with a second name that identifies the second result set;
• labeling elements of the second result set with the second name that identifies the second result set, wherein the labeling presents the first and second modifiable queries upon a user selection;
• determining a change in either the first modifiable query or second modifiable query;
• and
• automatically updating the second result set, without additional user involvement, to reflect the change in either the first modifiable query or the second modifiable query.
