Keywords mentioned within double quotes, fetch results matching with the exact keyword.

For the in-depth forensic email search, the general search option of the forensic email search tool supports various searching algorithms such as “General search, Wild card search, Regular expression, Fuzzy search, Stem search”. Each of the algorithms help the investigators to search for the desired emails according to the various assumptions. The General Forensic Search method can further be narrowed down to be more specific, by searching for keywords in specific fields.

General Search

Proximity Search – A Hit & Trial Method

It will search for the email data with two or more words and the approximate distance between them. Distance means the number of characters separating that two words. This search evidence forensic can be executed by the Hit & Trial method.


Regular Expression

Regular Expression Search is the another advanced email search mechanism which searches the evidences in forensic email data using various combination of patterns. This searching mechanism use pattern matching to search for particular string rather than creating search queries.

Regular Expression Search

Stem Search

That is, if you search the word “road” it will give you the result like road, roadway, roadside and other similar results starts with road.
