With the SRU/Z39.50 search using a quotation mark has the interesting effect that the first page of a result is displayed but a second page is not available. Looking at the pl source it seems that quotation marks are used and escaped for the first page but not for a second recall.
Which version of Koha are you using? Can you give us an example of title with quotation mark to search for?
Version tested: Our operational System 16.05.02.000 Linux vbib 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) x86_64 Our test System 17.05.04.000 Linux vbib-dev 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) x86_64 The search string does not matter (tested for space in the brackets) it works for all quotations simply try "test" :-)
If I search for "test" (with quotation marks), I do not get any results at all. Could you give us more details to recreation the issue?
Then I have to enlarge the bug ;-) Library of Congress SRU gives NOTHING (you are right, but is this intended ?) Deutsche Natiional Bibliothek SRU services.dnb.de:80 gives the result Ive described Search Terms: meteorology "meteorology" Ive looked at /usr/share/koha/intranet/cgi-bin/cataloguing/z3950_search.pl and as I understands it its the same for z39.50 and SRU so if I want to fiddle its the right place to look right ?
Can you paste the complete configuration of the SRU server you configured?
You need an account (its free but you have to register) the ip-range of my institution can access (so no username and password) Hostname services.dnb.de Port 80 database sru/dnb Syntax MARC21/USMARC Coding UTF8 Options sru=get,sru_version=1.1, schema=MARC21-xml and the mapping of the Fields Titel: dnb.tit ISBN: dnb.num Controlnumber: dnb.idn free Text: dnb.woe Author: dnb.atr ISSN: dnb.num Keyword: dnb.sw Dewey: dnb.ddc Standard-ID: dnb.idn
Registration is no longer necessary for using the DNB SRU server, so this could be better tested now.
