Or, " (double quotation) in your query string may affect query parsing.
When I parse this string by classic query parser (lucene 8.1),
street="MAINS~"
parsed (raw) query is
text:street text:mains
(I set the default search field to "text", so text:xxxx is appeared here.)
Query parsing is a complex process, so it would be good to check
parsed raw query string especially when you have (reserved) special
characters in your query...
