Re: Boost matches occurring early in the field (offset)

The original question is interesting and also I'd like to boost terms with lower positions, but if it's possible with the payload stuff, the slides and the article at https://lucidworks.com/2017/09/14/solr-payloads/ left me completely confused. A simple complete example would be so great.

Re: Boost matches occurring early in the field (offset)

: I have seen that one. But as I understand spanFirst, it only allows you : to define a boost if your span matches, i.e. not a gradually lower score : the further down in the document the match is? I believe you are incorrect. Unless something has drastically changed in SpanQuery in the past

TokenOffsetPayloadTokenFilter ? It is mentioned in https://www.slideshare.net/lucidworks/payloads-in-solr-erik-hatcher-lucidworks , but no detailed example seems to be given. I do see this question from time to time, so a definitive feedback would be useful for the future. Regards, Alex. On

Re: Boost matches occurring early in the field (offset)

I also tend to use "sentinel tokens" for exact match or to anchor a search. But in order to obtain decaying boost the further down in the article a match is, you'd need to write several such span/slop queries with varying slops, e.g. highest boost for first 10 words, medium boost for first 50

Re: Boost matches occurring early in the field (offset)

You can also insert a token at the beginning of the query during analysis using a char filter. I call these sort of boundary tokens "sentinel tokens". So a phrase search for "red shoes" becomes " red shoes". You can add some slop to allow for permissible distance (with You can also use the Limit

Boost matches occurring early in the field (offset)

Hi, Is there an ootb way to boost term matches based on their position/offset inside a field, so that the term gets a higher score if it occurs in the befinning of the field and lower boost or a deboost if it occurs towards the end of a field? I know that I could index the first part of the
