algorithm - Is it indexing Or tagging? -


i have 2 classes claim , index. have field in claim class called topic string. m trying index topic column not using database index column features. should coding following method. suppose have claim 1, claim 1 topic field ("i love muffins muffins") ll folowing treatment

#1. create empty dictionary "word"=>occurrences #2. create list of stopwords exemple stopwords = ("for","this".....etc ) #3. create list of delimiters  exemple delimiter_chars = ",.;:!?" #4. split text(topic field) words delimited whitespace. #5. remove unwanted delimiter characters adjoining words. #6. remove stopwords. #7. remove duplicate #8. create multiple index object (word="love",occurences = 1,looked = 0,reference on claim 1),(word="muffins",occurences = 2,looked = 0,reference on claim 1),

now whenever word muffins exemple looked increase 1 , move record in database. question following method ? better database index features ? there someways improve things ?

what think looking called b-tree. in case, use 26 (or 54 if need case sensitivity) branch node in tree. make finding objects fast. think time nlogn or something. in node, have pointer actual data in array, list, file, or else.

however, unless willing put time in code specific application, might better off using database such oracle, microsoft sql server, or mysql because these professionally developed , profiled maximum performance possible.

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
