[TYPO3-Solr] Solr boost field

[Stephan Schuler]

Hey Csaba.

I think boosting is not what you want.

Imagine searching for “something” and have that expression in one documents “title” property and in another documents “body” property.
Boosting the title over body means that the document where “something” occurs in the “title” property is more worthy than the document where “something” occurs in the “body” property.
The number you always add to boosting indicate how much more worthy it is. You can have a document where “something” occurs only once in the title being calculated higher than a document where “something” occurs three times in the body, but less than a document where “something” occurs four times in the body.
That’s what boosting is for. Count occurrences of your search word and apply the boosting factor.

If you want to have actual sorting, you should use sorting.

You actually *have* sorting in a default setup. Only you don’t “sort by title” but you “sort by score”, where “score” is the calculation result including boost factors.

    Hi,

    i have a question regarding to boost search result by a given field. I
    need to make a custom extension which extend page properties on that way
    the user can add a value to a field(boost) will influence  the search
    result order by positioning. So far this thing i managed to do and with
    the following TS config the new field appear too in the solr index fields:

    plugin.tx_solr.index.queue {
         newfield = 1
           boostsearchresults {
             table = pages
             fields {
                     newfield_intS =     newfield_intS
             }
         }
    }

    ...

    So basicly i'm looking for some TS configuration to boost a page where
    this "newfield_intS" value is changed or it has a higher value than the
    other ones. I did some researches but didn't find yet the proper
    solution. Any help would be great, Thank you.
