To boost a document with DIH, see this section about "$docBoost" in the wiki here: http://wiki.apache.org/solr/DataImportHandler#Special_Commands.
If you're using a RDBMS for source data, your query would have something like this in it: "select PAGE_RANK as '$docBoost', ... from ... etc" If you don't want to boost entire documents but have it be very flexible at query time, see the page on Extended Dismax, especially the boost function section: http://wiki.apache.org/solr/ExtendedDisMax?highlight=%28edismax%29#bf_.28Boost_Function.2C_additive.29 . Also, the Packt Solr book (Smiley&Pugh) has a nice section about boosting scores based on page-rank or popularity type fields. In the old first edition its chapter 5, "enhanced searching".

That page explains how to do index-time boosting at record level, and field level for XML documents uploaded to Solr with post.sh. If you are using the Solr DataImportHandler, you can boost records, but not individual fields, as far as I am aware. Please take a look at this thread for an example: http://lucene.472066.n3.nabble.com/Index-time-boosting-with-DIH-td3206271.html It would help if you did some basic groundwork, tried out things for yourselves, and asked more specific questions.
