The primary way of specifying what content or source to search in is to specify it in the query attributes. <br><br>The reason for this is that content and source are not really fields, and some engines treat them very differently, making it hard to do boolean ops on them. In most cases ORing is easy because they can just search the individual content/sources and merge the results, but ANDing (and full boolean ops) require more work, that should be optional to support. <br></div><br></div>Cheers,<br>Mikkel<br>
