Hi Alex, My requirement is that I should be able to search for a person , for example Tom Hanks, by either
1) the whole of first name (Tom) 2) or partial first name with prefix (To ) 3) or partial first name without prefix ( om) 4) or the whole of surname ( Hanks) 5) or partial surname with prefix (Han) 6) or partial surname without prefix (ank) 7) or the whole name (Tom Hanks) 8) or partial first name with or without prefix and partial surname with or without prefix ( To Han , om ank) 9) All of the above as case insensitive search Thanks in advance for your help Regards, Dinesh Babu. -----Original Message----- From: Alexandre Rafalovitch [mailto:arafa...@gmail.com] Sent: 07 December 2014 01:20 To: solr-user Subject: Re: How to stop Solr tokenising search terms with spaces There is no spoon. And, there is no "phrase search". Certainly nothing that is one approach that fits all. What is actually happening is that you seem to want both phrase and prefix search. In your original question you did not explain the second part. So, you were given a solution for the first one. To get the second part, you now need to to put some sort of NGram into the index-type analyzer chain. But the problem is, you need to be very clear on what you want there. Do you want: 1) Major Hanks 2) Major Ha 3) Hanks Ma (swapped) 4) Hanks random text Major (swapped and apart) 4) Ha Ma (prefix on both words) 5) ha ma (lower case searches too) Or only some of those? Each of these things have implications and trade-offs. Once you know what you want to find, we can help you get there. Regards, Alex. P.s. If you are not sure what I am talking about with the analyzer chain, may I recommend my own book: http://www.amazon.ca/Instant-Apache-Solr-Indexing-Data-ebook/dp/B00D85K9XC It seems to be on sale right now.
