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

":" is a syntactically significant character to the query parser, so it's
getting confused by it in the text of your query.
you're seeing the same problem as if you tried to search for "foo:bar" in
the "yak" field using q=yak:foo:bar
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
characters (but remember that since you are building this up as a java
string, you have to deal with *java* string escaping as well...
String a = "speechDate:1992-07-10T17\\:33\\:18Z";
String a = "speechDate:\"1992-07-10T17:33:18Z\"";
String a = "speechDate:" +
ClientUtils.escapeQueryChars("1992-07-10T17:33:18Z");
String a = "{!field f=speechDate}1992-07-10T17:33:18Z";
: My goal is to group these speeches (hopefully using date math syntax). I would
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]";
(which doesn't require special escaping, because the query parser is smart
enough to know that ":" aren't special inside of the "[..]")
: like to know if you suggest me to use date or tdate or other because I have
: not understood the difference.
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.
