*Only* the matching whole sentence highlighted

[Li Leon <le...@gmail.com>]

Hi all,

I was able to get a whole sentence(including stop words) highlighted with
"StandardAnalyzer" and an empty stop words String[].

The current issue I'm having is that not only the whole sentence got
highlighted but those tokens partially match with the sentence also
highlighted. I tried to use "PhraseQuery" with the appropriate slop to make
only the intended sentence highlighted, but ended up with exception like
below.

My question is - is this a valid direction to go?


Exception in thread "main" java.lang.NoClassDefFoundError:

You need contrib-memory.jar in your classpath to use MemoryIndex.
