BUG 0000 herbert> SOLR implementation in PMOS2

Solr support in PMOS2 includes:
Functionality:
- Implementation of Home views (Inbox, Draft, Participated, Unassigned). The views return fast results.
- Include read, unread, all,  and process filter in inbox View.
- Include process filter in draft view.
- Include started by me, completed by me, all, process, and status filter in participated view.
- Include process filter in unassigned view.
- Improved search functionality (search in user defined variables): Use the following syntax to search in process (user defined) variables. {variable_name}:{search_word} ex1:"causal:20*" where causal is the variable defined by the user.
  + Use of wildcards in search: Use * as wildcard at the begin or end of word
  + Multiple conditions in search: Separate multiple conditions by space ex2:"Materiales causal:20*" means that we are searching for the word Materiales and the causal that begin with 20.
  + Search in dates (interval ): Format=> {variable_date}:[yyyy-mm-dd TO yyyy-mm-dd]
    Local date not UTC date required
    ex: FechaRegistro:[2011-04-15 TO 2011-04-30] //registros con fecha entre el 2011-04-15 y el 2011-04-30.
  + we can use the wildcard *:
    ex: FechaRegistro:[* TO 2011-04-30] //registros con fecha menor o igual a 2011-04-30.
    FechaRegistro:[2011-04-15 TO *] //registros con fecha mayor o igual a 2011-04-15.
  + Search of exact phrases. format: {variable}:"frase a buscar"
    ex: Cliente:"Jesus Marin"

- Application update function.
	+ The function is called every time a change is detected in the application's data including the related delegations.
- Use of cache to improve performance

Not included:
- Order of task, sent by, and due date columns.

Pending:
- Advanced search view using faceted lists.
