Search Tips

Use specific words to describe exactly what you are searching for.

• Ejemplo: E.g.: Search for "subscriber loop" instead of "decisions".

To search for an exact phrase, enter two or more words between inverted commas. If you do not use inverted commas, the search tool will display any web page in which any of the search terms appear, which is equivalent to inserting "OR" between the words in the search tool.

You can search for a word and its derivatives by adding an asterisk to the root (the terms "energy" or "energetic" will appear in the results if you search for "energ*")

A question mark can be used to represent any character.

• Ejemplo: E.g.: If "Not" is entered into the search tool, a search will immediately be carried out looking for any four letter words that begin with "Not".

In order to carry out more complex searches, combine the different terms using Boolean operators: AND, OR and NOT.

• Ejemplo: E.g.: When searching for terms where two or more alternatives exist, use OR. For example, search for "subscriber loop OR interconnection offer".

To include words, type the symbol + before each word.

• Ejemplo: E.g.: "+ press releases". The results displayed as a result of this search will contain the word "releases" and may contain the word "press".

To exclude words, type the symbol - before each word. This will have the same effect as the Boolean operator NOT.

The search tool does not distinguish between uppercase and lowercase. All letters are regarded as lowercase.

• Ejemplo: E.g.: "DECISION" or "decision" will generate the same results.

The search tool does not distinguish between accents, dieresis, the letter ñ or any other special orthographic marks. I.e. the same number of results will be displayed for "Martín" and "Martin.
