elasticsearch - Search WIthout Field Length Normalization -

how can omit fieldlength norm @ search time? have documents want search , want ignore extraneous strings in query things "parrot" match "multiple parrots."

so, how can ignore field length norm @ search time?

i had same problem - though think efficiency reasons done @ index time. instead of using tf-idf used bm25 (which supposedly better). bm25 has coefficient field norm term can set 0 doesn't effect solution...
