When store info, can store actual text and use BEX to parse it

For example, a method invocation or assignment can be stored with the entire statement (even if it spans multiple lines).

Ensure also index the pattern type so know how to parse - so as assignment, +=, -=, if condition, method invocation, etc.

Then, could index entire statement. Then, use BEX to parse on query to extract desired info. This should simplify the indexing process and also give a consistent way to query. Another benefit is the line is indexed, so of the pattern changes, don't need to reindex the line. This allows the pattern to evolve over time as needed.
