Re: Dynamic Boosting at query time with boost value as another fieldvalue
: ohk.. that means I can't use colon in the fieldname ever in such a scenario : ? In most internals, the lucene/solr code base allows *any* character in the field name, so you *can* use colons in field names, but many of the surface features (like the query parser) treat colon's as special characters, so in *some* situations colons don't work in field names. -Hoss
Re: Dynamic Boosting at query time with boost value as another fieldvalue
hi, Is it possible to have a fieldname with colon for example source:site? I want to apply query time boost as per recency to this field with the recency function. Recip function with rord isn't taking my source:site fieldname, its throwing an exception. I have tried with escape characters too. Please suggest something.

Re: Dynamic Boosting at query time with boost value as another fieldvalue
The colon is used to specify value for a field. E.g. in the query box of solr admin you would type something like fieldName:string to search (title:Java). You can use hypen '-' or some other character in the field name instead of colon.
