progress 4gl:how to retrive database record that satisfies all the keywords entered by user in fill-in-field -


the keywords entered user i.e number of keywords,it may 1 or more. take fill-in-field taking input , search pairs of keywords match database record means ,i display on browse...but record must satisfy keywords entered user,if not satisfied means,it display individual keyword result. thankyou sir-------the code write 

::::assign entrycount = (num-entries(hi:screen-value)).         repeat  pos = 1  entrycount :         assign keywordi = entry(pos,trim(hi:screen-value)).             each db1.vehicles vehicles.ad-num matches keywordi or string(vehicles.sl-num) matches keywordi                 or vehicles.product-id matches keywordi or vehicles.product-name matches keywordi or                 string(vehicles.amount) matches keywordi no-lock:             each db2.service  db2.service.ad-num = db1.vehicles.ad-num no-lock:     /*             if vcount eq 0 , scount lt 1 */     /*            do:                                  */                 find ttservice  ttservice.service-num = service.service-num no-lock no-error .                 if available ttservice                  do:                  end.                 else                 do:                  create  ttservice  .                 assign  ttservice.ad-num = vehicles.ad-num                          ttservice.sl-num = vehicles.sl-num                         ttservice.sl-id = service.sl-num                         ttservice.product-id = vehicles.product-id                         ttservice.service-num = service.service-num                         ttservice.product-name =vehicles.product-name                         ttservice.purchase-amt = vehicles.amount                         ttservice.service-amt = service.service-amt no-error .                 end.         end.

well, dynamic query wouldn't suffice here, because want search every entry against every field. , wouldn't work, because you're not adding wildcards -> * strings. see, in progress 

display 'myhappyexample' matches 'happy'.

returns false, while 

display 'myhappyexample' matches '*happy*'.

will give true state. amount of or clauses, added conversion of fields on left side, throw performance out window. if still pursue this, take @ answer posted on other thread

and if you'd pursue more elegant solution using dynamic queries (but should ask user select fields want filter, , build csv those, , enter filters in order of fields want search, @ answer posted:

in fact, i'd suggest interface user select fields wish filter, allow them enter values want filter specific field, use dynamic queries build that. more performance-wise efficient, in opinion.

anyway, let me know, hope helps.
