in a synonym Engine... suppose synonyms of word x is syn(x)...
then if y = syn(x) then x = syn(y) doesn't hold true always .....( you might not get any synonyms of y..it depends on the data of synonym engine) so your synonym engine might be providing alias of bob as robert, rob, bobby... so when you search for bob, you are getting results which contain robert,rob,bobby etc ( I am assuming that you are using the synonymanalyzer for parsing the queries not for building the index because if u r using synonymanalyzer for building the index, it reduces the performance by a great degree) When u r searching for robert and your synonym engine doesn't provide any synonyms for roberts as bob, bobby ...you will not get the desired result so you need to rewrite your engine so that it satisfies the above condition On 27/03/07, daveburns <[EMAIL PROTECTED]> wrote:
Hi, afriad I'm a noobie at Luncene but read Otis/Eriks book and was hoping someone can answer a quick question on the AliasAnalyzer (Chap 4). I want to build a search for names (Companies/surname, firstname etc) but need to match thing s like Robert= bob, bobby, rob etc (or margaret=peggy etc). 1) The problem is my search returns all Robert or Bob hit's if I search on bob but if I search on Robert only Robert hits come back. I though the index would automatically provide my required 2-way matching? 2) The second problem is to do with Company names. Can I create the above alias analyzer to match I.B.M=IBM=International Business Machines? i.e. multiple words to a single word.
