Search Parser
Search ParserSearch Parser
The Search Parser is a custom parser used to generate metadata by scanning for predefined keywords and regular expressions. The parser searches the payload of a reconstructed session for string matches and can execute a regular expression search. You can configure the parser by editing the search.ini file.
Caution: The search parser can have a significant impact on system performance. It is important that both the search mechanism and the data to which it is applied to be well understood before creating new search definitions and enabling the search parser.
The search definition is used across all protocols. There are three basic search methods:
- Keyword: Search a stream for a specific set of words
- Pattern: Search a stream for a regular expression match
- Keyword + Pattern: Search a stream for a regular expression if it contains any of a given set of keywords.
