Hi Jack, Reproducing the email that specifies my requirement.
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 Regards, Dinesh Babu. -----Original Message----- From: Jack Krupansky [mailto:j...@basetechnology.com] Sent: 07 December 2014 02:04 To: solr-user@lucene.apache.org Subject: Re: How to stop Solr tokenising search terms with spaces AFAIK, partial word matching is not a common use case. Could you provide a citation to shows otherwise? Solr does provide a "simple mechanism" for "phrase search" - just place your phrase in quotes. If you wish to do something more complex, then of course the solution may be more complex. The starting point would be for you to provide a more complete description of your use case, which is clearly not "simple phrase search". Your most recent messages suggested that you want to match on partial words, but... you need to be more specific - don't make us try to guess your requirements. Feeding us partial requirements, one partial requirement at a time is not particularly effective. Finally, are you really trying to match names within arbitrary text, or do you have a field that simply contains a complete name? Again, this comes back to providing us with more specific requirements. My guess, from your mention of LDAP, is that the field would contain only a name, but... that's me guessing when you need to be specific. Once this distinction is cleared up, we can then focus on solutions that work either for arbitrary text or single value fields. -- Jack Krupansky -----Original Message----- From: Dinesh Babu Sent: Saturday, December 6, 2014 7:17 PM To: solr-user@lucene.apache.org Subject: RE: How to stop Solr tokenising search terms with spaces Just curious, why solr does not provide a simple mechanism to do a phrase search ? It is a very common use case and it is very surprising that there is no straight forward, at least I have not found one after so much research, way to do it in Solr.

When I tested {!field} it seemed to work as the query was on such a data that it made to look like it is working. using the example that I originally mentioned to search for Tom Hanks Major 1) If I search {!field f=displayName}: Hanks Major, it works 2) If I provide partial word {!field f=displayName}: Hanks Ma, it does not work Is this how {!field is designed to work? Also I tried without and with escaping space as you suggested. It has the same issue 1) q= field1:"Hanks Major" , it works 2) q= field1:"Hanks Maj" , does not works Regards, Dinesh Babu. -----Original Message----- From: Erik Hatcher [mailto:erik.hatc...@gmail.com] Sent: 05 December 2014 16:44 To: solr-user@lucene.apache.org Subject: Re: How to stop Solr tokenising search terms with spaces But also, to spell out the more typical way to do that: q=field1:”…” OR field2:”…” The nice thing about {!field} is that the value doesn’t have to have quotes and deal with escaping issues, but if you just want phrase queries and quote/escaping isn’t a hassle maybe that’s cleaner for you.
