word position operator?

[Darren Govoni <da...@ontrenet.com>]

Hi,
  I want to do a query such as 

word: first*

where I want 'first' to be the start of the string value contained in the word field and not somewhere inside it.
What's the best way to do this?

thanks for any tips,
Darren

Hi Darren,

Check out SpanFirstQuery and SpanRegexQuery:
