A quick way to understand the formats and editing styles is by examples. Try to edit the following page and see how the page is formated with the query and different sections: Science Fiction about AI.
The editing interface consists of two parts, first the query input bars, and next the big text box for adding information associated with the query, such as the topic descriptions etc.
Generally, for the ease of creation and for other people to easily understand your queries, it would be better to put one concept in one input bar, and all the required concepts for the query (being entered into all different bars) will be joined by AND.
This way of separating concepts to different input bars also allows easier reuse of the already existing concepts. For example you can borrow the "Pittsburgh" concept from one query to another query that is also about Pittburgh.
Because of the reasons above, although entering the whole query in one line still works, it is less encouraged to do so.
The AND, OR and " " (phrase) operators work for both Google and Altavista. Here is a cheat sheet for Google's query operators and query language. Note, the - (not) operator works in Google but not Altavista, so a query containing "-" may not have the intended effect in Altavista.
When you are making a lot of changes to one page, try to save your changes frequently, in case of accidental loss of your changes.
The text box containing the page content can also have two parts, if the page is about a query.
The first part is automatically generated content for the structured query. This section is explicitly marked by comments saying "<!-- The query below is automatically generated, please don't edit. -->" and "<!-- Please start writing related information below: -->".
The rest of the article content should be information about the topic, for example topic description or intended uses of the topic. See Science Fiction about AI for an example.
You can use multiple sections to store different aspects of an information need. To start a new section, enter its title in a new line in the following form: == title ==
