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.

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.

Hi Erik,
Probably I celebrated too soon. 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.

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.

One more quick question Erik,
If I want to do search on multiple fields using {!field} do we have a
query similar to what {!prefix} has
: q={!prefix f=field1 v=$f1_val} OR {!prefix f=field2 v=$f2_val} where
&f1_val=<field 1 value>&f2_val=<field2 value>
Regards,
Dinesh Babu.

Thanks a lot Erik. {!field} seems to solve our issue. Much appreciate your
help

try using {!field} instead of {!prefix}. {!field} will create a phrase
query (or term query if it’s just one term) after analysis. [it also
could construct other query types if the analysis overlaps tokens, but
maybe not relevant here]
Also note that you can use multiple of these expressions if needed:
q={!prefix f=field1 v=$f1_val} OR {!prefix f=field2 v=$f2_val} where
&f1_val=<field 1 value>&f2_val=<field2 value>

Hi,
We are using Solr 4.10.2 to store user names from LDAP. I want Solr not
to tokenise my search term which has space in it Eg: If there is a user
by the name Tom Hanks Major, then
1) When I do a query for " Tom Hanks Major " , I don't want solr break
this search phrase and search for individual words (ie, Tom ,Hanks,
Major), but search for the whole phrase and get me the Tom Hanks Major
user
2) Also if I query for "Hanks Major" I should get the Tom Hanks Major
user back
We used !prefix, but that does no allow the scenario 2. Also !prefix will
restrict the search to one field and can't do on mutiple fields. Any
solutions?

Dinesh Babu.
