Question

Cfindex fieldboost does nothing - ColdFusion 2018

The documentation does not list fieldBoost in the list of valid attributes to cfindex, yet further down the page its function is described (see https://helpx.adobe.com/coldfusion/cfml-reference/coldfusion-tags/tags-i/cfindex.html ). It does not seem to have any effect on the cfindex tag. Has fieldBoost been removed (and how can we then boost a particular field) or has the syntax changed (and to what)? This is a ColdFusion 2018 Standard Edition running on Win Server 2016. 

Best, Robert

    Are you using 

     

    <cfindex fieldBoost="title">

     

    or

     

    <cfindex fieldBoost="title:3"> ?

     

    The usual recommendation is to use the second, which includes a weighting factor (3).

    Thank you so much for your answer, I have indeed tried both, but it does not seem to have any effect on the results returned. For instance: first I index without any fieldboost, and a search for "tax" returns this document with "tax" in the title. Then I reindex with "fieldboost:100" and expect the score to be higher, but it is unchanged. Is there perhaps any range limit for the boost value?

    Correction: I re-index with fieldBoost="title:100"
