Hi Team,High Query Time in Solr When Using OR with frange in fq We are experiencing high query times in Solr when using an fq filter that combines an OR condition with frange. The response time significantly increases compared to queries that do not use this combination. Query Example
fq={!cache=false tag=prm}field:value OR {!frange l=1 u=1 v=$funcQuery} Here, $funcQuery is a function query that retrieves documents dynamically based on dynamic parameters. Observations - When we use just {!frange l=1 u=1 v=$funcQuery}, the query executes quickly[20ms]. - When we use {!cache=false tag=prm}field: value alone, the query is also fast. - However, when combining both with OR, the query time increases significantly [700ms]. - The dataset is relatively large, but other queries with similar complexity run efficiently. Questions 1. Why does the OR operation with frange cause a significant increase in query time? 2. Are there any optimizations or alternative query structures that could improve performance? 3. Would it help to restructure how function queries and filters are applied in this case? 4. Is there any alternative for frange for this use case because in our use case, this cannot be done at index time because the function parameters change very frequently? Any insights or suggestions would be greatly appreciated!
