Let's assume we have a set of mp3-players with names and prices.
How to write a correct solr query for finding all goods with a certain name and with price less then 100$?
q = "(name:(ipod) AND price ???? 100.0)"
I don't think the query parser supports < operator. You have to define a RangeQuery explicitly. You can then attach a name query to that using a BooleanQuery.
Update: Apparently, I was wrong. In fact, Solr's query parser is smarter than Lucene's. Here is your answer: https://lucene.apache.org/solr/guide/8_0/the-standard-query-parser.html#differences-between-lucene-s-classic-query-parser-and-solr-s-standard-query-parser
field:[* TO 100] finds all field values less than or equal to 100
