Searching hyphenated words with Lucene

Question

I want lucene to search for hyphenated words, for eg: energy-efficient or "energy-efficient" as one single word

So if the input is energy-efficient the tokenizer generates terms like energy or efficient or energy efficient or energy-efficient

Therefore lucene returns with pages containing both "energy efficient" and "energy-efficient", but I want it to return exclusively with pages for energy-efficient

So the question is how can I modify the standardtokenizer to search for energy-efficient as one whole word and not break it into separate words.

Answer 1

Use WhitespaceAnalyzer instead of standardAnalyzer.
That will generate tokens dividing only on white space. But check for the other things that'll be changed.
