Oddity with edismax and queries involving boolean operators. Here's the
"parsedquery_toString" from two different queries:
input: "dog AND kiwi":
https://apaste.info/gaQl
input: "dog OR kiwi":
https://apaste.info/sBwa
Both queries return the same number of results (389). The query with OR was
expected to have a much higher numFound. Those pastes have a one week
lifetime.
The two parsed queries are almost identical. The AND query has a couple of
extra plus signs compared to the OR query, and the OR query has a ~2 after a
right paren that the AND query doesn't have. I'm at a loss as to what this
all means, except to say that it didn't turn out as expected.
Should the two queries have returned different numbers of results? If not,
why is that the case?
Here is the output from echoParams=all on the OR query:

If anyone has any ideas about whether this behavior is expected or
unexpected, I'd appreciate hearing them. It is Solr 7.1.0 with a patch for
SOLR-12243 applied.
There might be information that would be helpful that isn't provided. If
there is something else needed, please let me know, so I can provide it.
