Assuming you know how to write a portlet, if you don't, please check the documentation once.

Use Liferay core APIs to perform search. That's how document and library is working. Download the source code of liferay and check how document and media portlet works. You need to understand how it works, then it will be easier.

See this link: https://dev.liferay.com/develop/learning-paths/-/knowledge_base/6-2/beginning-liferay-development

And along with the development, keep an eye on portal source code. You can download portal source from sourceforge. http://sourceforge.net/projects/lportal/

You could also embed the search portlet (portlet id = 3) with an advanced configuration where by you limit the scope of the asset entries to just the Document Library entities (FileEntry and Folder). You can use the advaced configuration to adjust the facets that will show up as well. Here is an example of the out of the box Advanced configuration, modified to show only doucment library models, and all facets.

{"facets": [
    {
        "displayStyle": "scopes",
        "static": false,
        "weight": 1.6,
        "order": "OrderHitsDesc",
        "data": {
            "maxTerms": 10,
            "frequencyThreshold": 1,
            "showAssetCount": true
        },
        "className": "com.liferay.portal.kernel.search.facet.ScopeFacet",
        "label": "site",
        "fieldName": "groupId"
    },
    {
        "displayStyle": "asset_entries",
        "static": false,
        "weight": 1.5,
        "order": "OrderHitsDesc",

            "values": [
                "com.liferay.portlet.documentlibrary.model.DLFileEntry",
                "com.liferay.portlet.documentlibrary.model.DLFolder",
            ],
            "frequencyThreshold": 1
        },

Either way you should download the source for the portal to better understand the search API (as suggested). You should also download a tool called Luke (https://code.google.com/p/luke/downloads/list) which will allow you to query the index as you do a RDBMS tool. If you have not altered the stock configuration, your lucene data will be found in LIFERAY_HOME/data/lucene/<company_id>
