Are you trying to query for any numeric term at the start of a title or a 
specific numeric term at the start of a title?

Unless you are using a query parser that supports Lucene's SpanFirstQuery or 
SpanPositionRangeQuery, you have two choices:

1. Explicitly (or implicitly via a custom update processor) add a marker 
term so you can match beginning of title if you are looking for a specific 
numeric term, such as "markertext 123".

2. Add a second title field that is a "string" field type, say title_s, with 
a copyField from title to title_s, and then do a regex query to check for a 
digit at the beginning of the string form of the title, or use a trailing 
wildcard if you know the exact leading numeric value, such as "123 *".
