What I did was to just rewrite the actual search queries. If the 
user-provided query does not contain things like quotes/AND/OR then I will:
- replace all multi-whitespace with a single space
- remove any whitespace at the beginning and end of the search string (trim)
- replace any space by " AND "

In other words, I insert AND in between each word and then hand that 
modified query over to opencms. This searches for all words that the 
user proided. "Any words" (OR) is default behavior. Phrases can be 
searched for by enclosing the search query with double quotes. Exclude 
can be done by adding a minus "-" before each word that should be excluded.

Rewriting the query like this should be the easiest way.
