Hi,
I'm new to Solr and I'm trying to understand how relevancy is computed
in Solr. I've run across the following difference that puzzles me: I'm
seeing a difference between the "docFreq" returned by the debugQuery
output and the number of documents for that search term.
As understand docFreq it counts the number of documents that contain
each term for a given field - so to me that should match the number of
documents returned in a search.
E.g. Searching on a particular term below yields the following debug
output - 12 documents are found, but docFreq is 14. The total sum of all
occurrences of the term is somewhat higher.
"response": {
"numFound": 12,
...
"description": "weight(content_da:bil in 12)
...
"description": "fieldWeight in 12, product of:",
...
"description": "idf(docFreq=14, maxDocs=124616)"
...
"description": "fieldNorm(doc=12)"
Can someone enlighten me on what I'm missing?
Br,
Martin
