Hi - the thing you describe is possible when your set up uses SpanFirstQuery.
But to be sure what's going on you should post the debug output.

Hi Nielsen,
There is no special attention paid to first word. You are probably hitting
length normalisation.
Lucene/Solr punishes long documents, favours short documents.
(5 times appearing one) longer?

Interesting.
Most of the text fields are single word fields or close to it, but on some
of the documents, long text appears.
How long does a text need to be before hitting length normalization?

Hi,
I couldn't find any occurrence of SpanFirstQuery in either the schema.xml
or solrconfig.xml files.
This is the query i used with debug=results.

Hi,
length normal is computed for every document at index time. I think it is
1/sqrt(number of terms). Please see section 6. norm(t,d) at
https://lucene.apache.org/core/4_7_0/core/org/apache/lucene/search/similarities/TFIDFSimilarity.html
If you don't care about length normalisation, you can
Is there any general setting that removes this punishment or must
omitNorms=false be part of every field definition?

Hi David,
omitNorms=true will cause additional performance gains too.

To globally disable length norm, one can create a custom similarity and
register it as a default similarity though.

yes david you must use the omitNorms=true for great performance
Thanks
