This is the class you need to import in order to use escapeQueryChars: http://lucene.apache.org/solr/4_10_2/solr-solrj/org/apache/solr/client/solrj/util/ClientUtils.html Thanks, Shawn
Re: Invalid Date String:'1992-07-10T17'
Thanks very much for each of your replies. These resolved my problem and
teach me something important.
I have just discovered that I have another problem but I guess that I
have to open another discussion.
Cheers,
Mirko

you're seeing the same problem as if you tried to search for foo:bar in

you either need to backslash escape the : characters, or wrap the date
in quotes, or use a diff parser that doesn't treat colons as special

Unless you are truely seraching for only documents that have an *exact*
date value matching your input (down to the millisecond) then seraching or
a single date value is almost certainly not what you want -- you most
likely want to do a range search...
String a = speechDate:[1992-07-10T00:00:00Z TO 1992-07-11T00:00:00Z];

the difference between date and tdate has to do with how you wnat to trade
index size (on disk in ram) with search speed for range queries like
these -- tdate takes up a little more room in the index, but came make
range queries faster.

You'll need to wrap the date in quotes, since it contains a colon: String a = speechDate:\1992-07-10T17:33:18Z\; -Michael -Original Message- From: Mirko Torrisi [mailto:mirko.torr...@ucdconnect.ie] Sent: Tuesday, March 10, 2015 3:34 PM To: solr-user@lucene.apache.org Subject: Invalid Date String:'1992-07-10T17' Hi all, I am very new with Solr (and Lucene) and I use the last version of it.
