solr dismax identify phrase match

Question

I am searching for "i want honda bike" on a text field using edismax query handler.

My intent is to find out docs having "honda bike" in it.

Now the results containing "honda", "bike" and "honda bike". Basically I am not interest in "honda" and "bike". I am actually interested in "honda bike".

Is there any way to identify if the phrase in field has matched the user query?

Answer 1

The problem was IDF was disturbing the score hence I could not fully rely on score to confidently say what has perfectly matched. So I disabled IDF calculation.

take a look at

Answer 2

I would investigate these parameters -- pf, pf2, and pf3.

pf -- phrase fields. This will let you boost the documents that have your q values in close proximity.

pf2 and pf3 -- chops the input into bigrams (or trigrams).

There are also slop settings to give some leeway in matching.

Answer 3

mm (Minimum 'Should' Match) feature of edismax can be used here
