Code search using multiple search strings, matched using AND/OR

I'd like to be able to perform a Code search in the SF using multiple search strings, instead of the one string we currently provide. I'd also like to specify if the search should match all (AND) or match any (OR) of the conditions.

Example 1:

• Search for code that contains “model_id” AND “branch_id”.

Example 2:

• Search for code that contains “status = ‘planned’” OR “status = ‘in_progress’”
