     * Transform plain text for highlighting search terms, ie in the

     * preview window or result list entries.

     *

     * The actual tags used for highlighting and anchoring are

     * determined by deriving from this class which handles the searching for

     * terms and groups, but there is an assumption that the output will be

     * html-like: we escape characters like < or &

     * 

     * Finding the search terms is relatively complicated because of

     * phrase/near searches, which need group highlights. As a matter

     * of simplification, we handle "phrase" as "near", not filtering

     * on word order.

     *

     * @param in    raw text out of internfile.

     * @param out   rich text output, divided in chunks (to help our caller

     *   avoid inserting half tags into textedit which doesnt like it)

     * @param hdata terms and groups to be highlighted. These are

     *   lowercase and unaccented.

     * @param chunksize max size of chunks in output list
