Check for EdgeNGramFilterFactory filter

<filter class="solr.EdgeNGramFilterFactory" minGramSize="3" maxGramSize="25" side="front"/>

EdgeNGramFilterFactory generates edge grams for the token e.g.

word would generate -> wo, wor, word .....

You can use this at index time to generate the tokens. So when you search for wor, documents with word would match

However, if you want to search in the mid of the words check for NGramFilterFactory

treat the number as string with edge gram filter applied. – Jayendra Jul 15 '13 at 07:48
