The query treatment is probably correct, because the default operator is
"AND", so when "and" gets treated as a stop word and ignored the default
operator is still AND, but when "or" is treated as a stop word and ignored
the operator changes from "OR" to the default implicit "AND".

Subject: Edismax lowercaseOperators=false does not ignore lowercase and
Hi,
I could not prevent users from using and/or with their search so I just
thought to add and/or in my stopwords.txt. However solr, configured with
edismax, lowercaseOperators=false, still treats "and" as an operator. To
illustrate below are the generated parsedQueries for the search term spoon
(and|AND|or|OR) fork. Notice that or/OR generated different queries while
and/AND generated the same queries. My assumption was, the generated query
for the lowercase and should be the same as the lowercase or since both
words were "stopped".
spoon and fork
+(+DisjunctionMaxQuery((id:spoon^10.0 | cat:spoon | ((text:spoon
text:spoon)^0.5) | manu:spoon^1.1 | sku:spoon^1.5 | name:spoon^1.4))
+DisjunctionMaxQuery((id:fork^10.0 | cat:fork | text:fork^0.5 |
manu:fork^1.1 | sku:fork^1.5 | name:fork^1.4)))
spoon AND fork
+(+DisjunctionMaxQuery((id:spoon^10.0 | cat:spoon | ((text:spoon
text:spoon)^0.5) | manu:spoon^1.1 | sku:spoon^1.5 | name:spoon^1.4))
+DisjunctionMaxQuery((id:fork^10.0 | cat:fork | text:fork^0.5 |
manu:fork^1.1 | sku:fork^1.5 | name:fork^1.4)))
spoon or fork
+((DisjunctionMaxQuery((id:spoon^10.0 | cat:spoon | ((text:spoon
text:spoon)^0.5) | manu:spoon^1.1 | sku:spoon^1.5 | name:spoon^1.4))
DisjunctionMaxQuery((id:fork^10.0 | cat:fork | text:fork^0.5 | manu:fork^1.1
| sku:fork^1.5 | name:fork^1.4)))~2)
spoon OR fork
+(DisjunctionMaxQuery((id:spoon^10.0 | cat:spoon | ((text:spoon
text:spoon)^0.5) | manu:spoon^1.1 | sku:spoon^1.5 | name:spoon^1.4))
DisjunctionMaxQuery((id:fork^10.0 | cat:fork | text:fork^0.5 | manu:fork^1.1
| sku:fork^1.5 | name:fork^1.4)))
my config is below:
