can someone point to any usage of PayloadScoreQuery class from Lucene please?

Best regards

Another piece resolved: DefaultSimilarity is now ClassicSimilarity since LUCENE VERSION 5.4.

One thing i noticed is that org.apache.lucene.index.IndexWriter class does not have setSimilarity and it is moved to

org.apache.lucene.index.IndexWriterConfig class. thus, i resolved the first question below.

org.apache.lucene.index.IndexWriter class does not have setSimilarity method, am i missing something for this?

i checked multiple Lucene versions.


next, i have this problem:

After defining the Analyzer as the PayloadAnalyzer like on the blog mentioned before,

i declared org.apache.lucene.search.QueryParser (with the analyzer mentioned above as the parameter) which was then used in declaring the org.apache.lucene.search.Query object via parse method of parser.

Now, i wonder how i can use PayloadScoreQuery in this scenario.

i mean i know the function of BoostingTermQuery class:

The BoostingTermQuery is very similar to the SpanTermQuery except that it factors in the value of the payload located at each of the positions where the Term occurs.

In order to take advantage of this, you must override Similarity.scorePayload(String, byte[],int,int) which returns 1 by default.

Payload scores are averaged across term occurrences in the document.


what i am asking is as follows:

Does this mean this (BoostingTermQuery in Lucene 2.9 or PayloadScoerQuery in latest Lucene) needs to be called for ***all the words*** scored in the format i mentioned <data>|<payload or score> in the data?

Sure, can You please point me to the location under Lucene Solr?

In Grant's article:

i want to know the need to use BoostingTermQuery (now in latest version PayloadScoreQuery)

where we already specify payloads in the data in the form <data>|<payload or score>.

Best regards

Maybe look at the Solr payload code to see how to do it in Lucene?

But yeah, that article is quite out of date.

Thanks i saw these posts but Grant's article is based on Lucene.

i am not using Solr. Many classes in that article does not exist in latest
versions of Lucene like version 6.1.

For instance BoostingTermQuery does not exist in 6.1 and the way docs are
indexed are also different on 6.1.

There is a new class PayloadScoreQuery but there is no examples like this
great article how to put them together.

Best regards
