How to get a better Lucene/Solr score if word queried was at the beginning of the indexed field?

问题

I read at some point something explaining what to do to have Lucene/Solr give a better score if my queried word was found at the beginning of the description I indexed. Cannot find it anymore on the net. Anybody has the links handy ? Thank you.

Payloads could help you do that. Actually, payloads let you give an arbitrary boost to any token of your token stream, so you can boost depending on anything:

• the position in the stream,
• the font weight,
• whether the token contains capital letters,
• ...

You can read more about payloads in this nice post from Grant Ingersoll.
