Hi all,
I found the fix for this issue and if anyone needs the fix, I'll
explain. How I explained before, my idea was escape special characters
before they will be sent to solr. This process is being done in the
following classes:
/dspace-1.7.2-src-release/dspace-discovery/dspace-discovery-xmlui-api/src/main/java/org/dspace/app/xmlui/aspect/discovery/AbstractSearch.java
/dspace-1.7.2-src-release/dspace-discovery/dspace-discovery-xmlui-api/src/main/java/org/dspace/app/xmlui/aspect/discovery/AbstractSearch.java
In this classes I added escapeQueryChars function from solrj, who adds
escape char before special characters on a string, and returns it well
formatted. Next step is use this function in generateURL function:
protected String generateURL(Map<String, String> parameters)
throws UIException {
String query = getQuery();
if (!"".equals(query))
{
query = escapeQueryChars(query);
parameters.put("query", encodeForURL(query));
}
Of course, if anyone knows a better solution will be welcome.
Regards

Hi Adan,
It seems well, but it changes the type of the search that is executed.
I think surrounding the query with quotes makes solr search the
literal string, and only returns the searches which contains the
exactly string entered. If you escape "?" character, the results list
is different because executes a normal search, I don't know if I
explained well....
Also thanks because it's interesting to learn tricks to search.

Hi Rubén
Try surronding the query between quotes. This can work in most cases,
unless the special character is a quote, of course

Hi,
I noticed that if I use special characters in advanced search, solr
doesn't return any results. I read in Lucene documentation that is
possible to escape these special characters adding "\" in front of them,
and I will ask you if it's possible to modify the string query adding
the escape character before send it to search engine, and if it's
possible, how can I do it.
Thanks in advance
