Searching -food, on google gives no result -

-

i fooling around, , going search food on google. mistake entered -food, , google gave no results:

your search - -food - did not match documents.

suggestions:

  • make sure words spelled correctly.

  • try different keywords.

  • try more general keywords.

i tried searching other keywords on google - before them. of them gave no results. knew because of part of algorithm, not understand part.

can tell me bug, or if isn't, how happening? part of algorithm causing this?

note: not off-topic asking algorithm. giving space after - gives proper results. like: - food.

even though off-topic. answer this, because transferred other site.

anyways..

you should read google search guide understand why happening.

this feature provided google search engine. when not want word appear in results of search, use hyphen before word. -animals.

consider this, want search sports cars without ferrari result. type sports cars -ferrari

so when -ferrari entering empty string in search box, , asking ferrari word absent results. results empty, entered empty string searched.

giving space in between, - food amount searching food , removing results word <null>, since there in nothing after hyphen. why giving proper results.
