How to search phonetic misspelled word in Lucene?

Here is the Scenario of Lucene Searching,

In Lucene document contains two fields having values "Red" and "Red Feather".

I want to search Red Feathar.

It is returning "Red" as first result. But I want "Red Feather" as first result.

I tried using fuzzy query term matches. but its makes my application slow.

So is there any another way to search Phonetic misspelled word in Lucene?

Thanks,

There are Phonetic matching methods in Lucene, but I think a FuzzyQuery is the right choice for this case. There are a few ways to enhance it's performance:

  • Are you using Lucene 4.0 or later? FuzzyQuery performance got a huge boost in 4.0.

  • Set a prefixLength. This forces the first x characters to directly match, which narrows searching for matching terms significantly, and takes better advantage of lucene's indexing methods, leading to significantly improved performance.

  • If you are using 3.6 or earlier (and can't switch to a more recent version), make sure you set minimumSimilarity

  • If you are using 4.0 or later, you could try setting maxEdits to 1
