Hi everyone, I'm indexing my data into multiple Solr fields, such as A, B, C and I'm also copying all the data of those fields into a master field such as X.
By default, my "qf" is set to X so anytime a user is searching they are searching across the data that also exist in fields A, B and C. In some use cases, I need to narrow down a user's search to just A and C or A only, etc. When that happens, I dynamically, at run time set "qf" to "A C" or just "A". My question is this, will the search quality and ranking be different if I simply set "qf" to "A B C" and avoid the copy operation to "X" (it will save me disk space)? Will there be a performance impact if I do this? Is there a limit at which point I should not list more than N fields in "qf"? Thanks, Steven
