Hi,
I need to filter the most relevant results. For example, a search for concrete and museum returns these results:

Concrete
painted concrete
Concrete with iron
Museum,
The Metropolitan Museum of Art.

it is possible make a filter to return only the following result: Concrete and Museum?

I'm using StandardTokenizerFactory.

Hi,
by default Lucene will always return the "most relevant" results on the top. That means that in your example "painted concrete" is having a higher scoring factor than "Museum".
That's probably correct based on the scoring formula, but I understand it's not what you want. The explanation is probably that "Concrete" has a higher value than "Museum".. I would suggest to project explanations of the scoring so you can better understand why this is the case.
