Lucene - Wildcards in phrases

Question

I am currently attempting to use Lucene to search data populated in an index.

I can match on exact phrases by enclosing it in brackets (i.e. \"Processing Documents\"

Answer 1

Another alternative is to use NGrams and specifically the EdgeNGram. http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.EdgeNGramFilterFactory

This will create indexes for ngrams or parts of words. Documents, with a min ngram size of 5 and max ngram size of 8, would index: Docum Docume Document Documents

There is a bit of a tradeoff for index size and time. One of the Solr books quotes as a rough guide: Indexing takes 10 times longer Uses 5 times more disk space Creates 6 times more distinct terms.

However, the EdgeNGram will do better than that.

You do need to make sure that you don't submit wildcard character in your queries. As you aren't doing a wildcard search, you are matching a search term on ngrams(parts of words).
