Using jquery and jquery-ui libraries we'll try to setup the autocomplete functionality on every textbox of advanced search page, we'll take advantage of Discovery Solr cores to add an additional search core for JSPUI. Check first on development server before moving this modifications to production

Note: This implementation will display only words or partial words when using autocomplete funcionality because JSPUI indexes fields splitting it in words and removing some suffixes, this is bad for searching full text like author names. In a future section I will describe how to set custom text indexers to our custom fields.

Once finished our textboxes must work like this:

...

We'll use a servlet class to query a SOLR core to generate a JSON responseresponses, this response responses will be wired to a textbox with autocomplete functionality. Here is a simple diagram of this dataflow.

...

We'll create a new folder inside \[dspace-source\]/dspace-jspui/dspace-jspui-webapp/src/main/webapp/static/js/*jqueryui* and copy all previously described files inside it.. Structure will look like this:

• Wiki Markup
  \[dspace-source\]/dspace-jspui/dspace-jspui-webapp/src/main/webapp/static/js/jqueryui/*{_}jquery-1.7.2.min.js{_}*

• Wiki Markup
  \[dspace-source\]/dspace-jspui/dspace-jspui-webapp/src/main/webapp/static/js/jqueryui/*{_}jquery-ui-1.8.21.custom.min.js{_}*

• Wiki Markup
  \[dspace-source\]/dspace-jspui/dspace-jspui-webapp/src/main/webapp/static/js/jqueryui/*css/...*

We'll edit \[dspace-source\]/dspace-jspui/dspace-jspui-webapp/src/main/webapp/search/advanced.jsp

Creating a new SOLR core

Now we must create a new SOLR core inside \[dspace-source\]/solr directory. To do so we'll use one of the existing cores and copy it's structure with this command:

bash$ cp -R [dspace-source]/dspace/solr/search [dspace-source]/dspace/solr/searchJSPUI
bash$ mkdir [dspace-source]/dspace/solr/searchJSPUI/data
bash$ mkdir [dspace-source]/dspace/solr/searchJSPUI/data/index

We'll edit \[dspace-source\]/dspace/solr/solr.xml and add one extra line with our new search core.

...

Now we'll modify new solr core configuration file \[dspace-source\]/dspace/solr/searchJSPUI/conf/schema.xml
\\
\\
\\ to handle lucene generated indexes:

Then we'll edit \[dspace-source\]/dspace/config/dspace.cfg and modify default JSPUI search index folder: 

# Where to put search index files
search.dir = ${dspace.dir}/solr/searchJSPUI/data/index
