How to Search

Single term query
- Just type the term you are looking for, taking account the search engine is case insensitive.
Complex queries
- Basic operators:
  - and: all the terms must appear in the document.
    city and sustainable
  - or: at least one of the terms must appear in the document.
    sustainable or durable
  - not: the subsecuent term must not appear
    movility not traffic
- Grouping:
  - Terms groups: all the previous operators can be included between brackets, allowing more complex combinations: ( ... ); you must notice that a space blank is required between search terms and brackets.
    ( social not economic ) and development
  - Literal phrases: you must sorround the search phrase between braces: {...}
    {sustainable development}
  - Substring matching: using the sign *, you can search prefixes, sufixes and words:
    inter* might substitute international or intergovernmental *national might substitute international or national sustain* and ( eco* not econom* )
  - Regular expressions: you can build even more complicated search terms between slashes /.../ (quite perl compatible).
    /pro(gra|ble)ms?/ might sustitute program or programs or problem or problems
You can select the number of results shown (documents are ordered by the number of hits appeared)
