I am using SOLR 7.1
ClassicSimilarityFactory
I have data in my core with field called CompanyName in an indexed field
IDX_CompanyName
<field name="IDX_CompanyName " type="text_general" indexed="true"
stored="false" multiValued="true" />
<field name="CompanyName" type="string" indexed="true" stored="true"/>
<copyField source="CompanyName" dest=" IDX_CompanyName"/>
Here are a few of the 900,000 rows in the core
Cityview
Citadel
CivicVentures
Clutch City Sports
Clutch City Sports & Entertainment
Clutch City Sports & Entertainment
Clutch City Sports & Entertainment
If I search for IDX_Company:(clutch AND city) and a fl=*,score and maxrows of
750, and at 1500 I get the following results
CompanyName Score
Cityview 5.874983
Citadel 5.3502507
CivicVentures 4.7278214
<other rows, but no clutch city>
If I search for IDX_Company:(clutch AND city) and a maxrows of 5000 I get the
following results
CompanyName Score
Cityview
5.874983
Citadel
5.3502507
CivicVentures
4.7278214
Clutch City Sports & Entertainment 3.6542892
Clutch City Sports & Entertainment 3.6542892
Clutch City Sports & Entertainment 3.6542892
Ive tried looking at the debug query to figure out what its doing and I'm
confused by what it is saying
The debug info for Cityview is
<str name="366640">
5.874983 = sum of:
1.9583277 = weight(Synonym(IDX_CompanyName:c IDX_ CompanyName:cl IDX_

</str>
Why would something with 2 hits score lower? Why does the max rows influence
this?
How might I fix this?
This didn't used to happen in SOLR 4.10 (I know its an older version, but...)
