Customizing Search Module in DSpace

Dear All,

I'm new to DSpace and I have a requirement of record and display zero search results. Eg:- If you search items by "Test", if the search result is zero, I have to record it and should be able to generate a report.

Any possibility of doing that with configurations or is there any one developed such kind of a module? Please Help.

Best Regards,

Masha

Re: Customizing Search Module in DSpace

Hi Masha,

Here's one way to find where in the code this happens.

Search for your fake string, and find the exact string it says for no search results.

"Search produced no results."

Look for this string in the code.

<message key="xmlui.ArtifactBrowser.AbstractSearch.no_results">Search produced no results.</message>

https://github.com/DSpace/DSpace/blob/master/dspace-xmlui/dspace-xmlui-webapp/src/main/webapp/i18n/messages.xml#L94

Then look for usages of xmlui.ArtifactBrowser.AbstractSearch.no_results in the code.

private static final Message T_no_results =

message("xmlui.ArtifactBrowser.AbstractSearch.no_results");

https://github.com/DSpace/DSpace/blob/master/dspace-xmlui/dspace-xmlui-api/src/main/java/org/dspace/app/xmlui/aspect/artifactbrowser/AbstractSearch.java#L84

Then, find usages of T_no_results in that class.

else

{

results.addPara(T_no_results);

}

https://github.com/DSpace/DSpace/blob/master/dspace-xmlui/dspace-xmlui-api/src/main/java/org/dspace/app/xmlui/aspect/artifactbrowser/AbstractSearch.java#L326

You then have your entry point where you have a chance to do an action where there are no results. For starters, you can write a message to log.info.

Re: Customizing Search Module in DSpace

Hi Peter,

Sorry I forgot to mention, I'm using JSPUI. I think the way it works is different in JSPUI. Any Idea?

Also I need to record no result searches in the database for reporting purposes.

Re: Customizing Search Module in DSpace

Hi Masha,

For JSPUI, you can follow the same process I showed you. Do a string search over the DSpace code-base, for each piece that your looking for, and look for where the hit is used. It helps if you check out the DSpace code into an IDE such as Intellij, NetBeans, or Eclipse. Otherwise, if your on *nix, you can grep it, otherwise, just Google it.

For JSPUI, here's the first hit you can start chasing: https://github.com/DSpace/DSpace/blob/master/dspace-api/src/main/resources/Messages.properties#L821

To log all of these empty-queries to a database, well, you could do that. You'd need to make a new table, add a class to interact with that table, have some setters and getters. You could also build a reporting page to show your empty queries, or just manipulate this data raw from SQL.

I would probably just log that there was no results, fire a usage event, have Spring wire up a listener to that event, and perhaps log that event into something like Solr, or elastic search. Or, just write to the dspace.log, and build a cronjob that parses your dspace.log each night, and throws all the entries for "No search results for query: quijibo" into whatever datastore you want from there.

Re: Customizing Search Module in DSpace

Hi Peter,

I'm in the middle of developing this. It will be very helpful if you can provide me a sample code if available.

Thanks,
Masha
