BUG#29445 - match ... against () never returns

Browse Source 
Part 1:
Do not perform index search for a plus-word with truncation operator
in case there are other plus-words in expression.

Specifically this optimization was enforced for expression like
"+word1 +word2*", but wasn't enforced for expression like
"+word1 word2*".
