of matching in Hamiltonian distances, such as the Hamiltonian distances of hobby and DOBBD,HOCBE are 2voidNearsearch (Tptr p,Char*s,intD//S is the string to look up, and D is the Hamiltonian distance{ if(p = = NULL | | D 0) return ; if(D >0|| *s s) {Nearsearch (P-Lokid, S, D); } if(D >0|| *s > P->s) {Nearsearch (P-Hikid, S, D); } if(P->s = =' /') { if((int) strlen (s) d) {printf ("%s\n", (Char*) p->eqkid); } } Else{nearsearch (P->eqkid, *s?

two applications: Fuzzy queries, a string containing a common prefix, and an adjacent query (the Hamilton distance is smaller than a certain range)Fuzzy searchPsearch ("root", ". A. a") should be able to match strings such as baxaca and cadakd. Void initialize arch1 (tptr P, char * s) {If (P = NULL) {return;} If (* s = '. '| * S Solve the Problem of matching within the Hamilton distance. For example, the Hamilton distance between Hober, dobbd, and hocbe is 2. Void nearsearch (tptr P, char * s,

presearch method. The first two are forward pre-searches, and the last two are reverse pre-searches. Of course, other translations actually mean one thing, you just need to know.These four expressions are similar to non-captured expressions in that they do not save the matching results to the capture group. The difference is that non-capturing group matches the content, although it is not saved to the capture group, it actually exists in the result $

is implemented through csmodule in CS. Csevent defines most events in the system. Events that contain users, posts, sections, groups, postcategories, ratings, favorites, exceptions, search, userinvitations, and other objects. However, every event calls the corresponding event function of the csapplication instance. For example, search events: public static void presearch (searchquery query) {csapplication. instance (). executepresearch (query);} publ

We often want to implement similar provinces and cities, the same function, the common is two search control, one selected the province, the other city's search control is automatically filtered, only show the current save the city, not all the city. Of course, this is the simplest, and there are more complex functions in the actual work to be implemented by filtering the lookup controls. This article mainly introduces the basic search control filtering, the complex filtering of multi-table asso
