elasticsearch - Difference between Elastic Search and Google Search Appliance page ranking -

-

how page ranking in elastic search work. once create index there underlying intelligent layer creates metadata repository , provides results query based on relevance. have created several indices , want know how results ordered once query provided. , there way influence these results based on relationships between different records.

do mean how documents scored in elasticsearch? or talking 'page-rank' in elasticsearch?

documents scored based on how query matches document. approach based on tf-idf concept term frequency–inverse document frequency. there is, however, no 'page-rank' in elasticsearch. 'page-rank' takes consideration how many documents point towards given document. document many in-links weighted higher other. meant reflect fact whether document authoritative or not.

in elasticsearch, however, relations between documents not taken account when comes scoring.
