In a July 2004 message (http://issues.apache.org/eyebrowse/[EMAIL PROTECTED]&msgId=1757461 but the list archives seem to be down right now), Martin Stein quoted Doug Cutting as giving this formula to estimate the amount of memory consumed by a query:
1 byte * Number of searchable fields in your index * Number of docs in your index plus 1k bytes * number of terms in query plus 1k bytes * number of phrase terms in query I'm adding some features to LIMO, and query RAM estimation is one of them. However, I'm not quite sure about how to calculate the first term in this formula. I'm calculating the memory used recursively. Does the first part apply to every Query object, or only to the entire Query structure? For example, with a query like "foo" on an index with 10 fields and 1000 documents, the memory used would = 1*10*1000 + 1024*1 = 11024. But for the query "foo +(bar baz)" do you include number_of_fields * number_of_documents part for each term in the query? Or just for the entire thing?
