Hello Teodor, Teodor Sigaev wrote: > byte offset of word is useless for ranking purpose Why is a word number more meaningful for ranking? Are the first 100 words more important than the rest? That seems as ambiguous as saying the first 1000 bytes are more important, no?
No, the first X aren't more important, but being able to determine word proximity is very important for partial phrase matching and ranking. The closer the words, the "better" the match, all else being equal. -- Mike Rylander mrylander(at)gmail(dot)com GPLS -- PINES Development Database Developer http://open-ils.org
