You might try www.Splainer.io - it will help you see where the matches
are happening.

Mónica - that is a surprising difference. Could you add &debug=true and share
the parsed queries you're getting in both cases?
What is the layout of your collection? multi-sharded? how many shards? Is
the index in flux (things being added or deleted) between those queries? Any
other architecturally relevant factors involved?
Best,
Erik

Hi,
I am using Solr 7.7 in Cloud with the default query parser and similarity
algorithm. I get the following results with these queries:
q= "Wolfgang Amadeus Mozart": 8834 results.
q= "Wolfgang Amadeus Mozart" OR "Wolfgang Amadeus Mozart": 8831 results.
To my surprise, I get 3 fewer results with the second query, and I have
seen that those 3 documents contain the same words in a different order
("Mozart Wolfgang Amadeus").
In case it is relevant, the field used for the query is a textual field,
with regular normalization (see below):
<fieldType name="text_general" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory" />
<filter class="solr.WordDelimiterGraphFilterFactory"
splitOnNumerics="0"/>
<filter class="solr.FlattenGraphFilterFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.ASCIIFoldingFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory" />
<filter class="solr.WordDelimiterGraphFilterFactory"
splitOnNumerics="0"/>
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.ASCIIFoldingFilterFactory"/>
</analyzer>
</fieldType>
Does anybody know why this is happening?
Thanks in advance for your help.
Mónica
