Knowledge Base

The wiki is the base for the Knowledge Base which we intend to rival that of the biggest companies for the benefit of our current and future members. Wikipedia is the ultimate model of a successful wiki, with a useful body of knowledge that has been built up by many contributors. A wiki is by definition always a work in progress as more and more information gets added to the site.

The problem with the forum is that the posts disappear over time. The wiki allows the construction of a web site with links to make it easy to find what you are looking for. At the moment it is still a bit bare but eventually it will rival the knowledge of the most experienced RGIs in the country. The wiki we use also allows Blogs and Surveys and the collection of News Articles in the style of Google News.

By signing up to the forum you automatically have access to the wiki, and you are welcome to contribute. The easiest thing is to go to a page that someone has already created and edit and add to their contribution. The next stage is to learn how to create links (internal and external).

We are always looking for editors, who are a bit like forum moderators, who will edit and tidy up sections of the site.

Search box


Non Advanced Search or Natural Search

The documents are returned sorted on relevance depending on order, proximity, frequency of terms.

Advanced Search or Boolean Search

Default search behavior

By default, all search terms are optional. It behaves like an OR logic. Objects that contain the more terms are rated higher in the results and will appear first in their type. For example, wiki forum will find:

  • objects that include both terms
  • objects that include the term wiki
  • objects that include the term forum

Requiring terms

Add a plus sign ( + ) before a term to indicate that the term must appear in results. Example: +wiki forum will find objects containing at least wiki. Objects with both terms and many occurences of the terms will appear first.

Excluding terms

Add a minus sign ( - ) before a term to indicate that the term must not appear in the results. To reduce a term's value without completely excluding it, use a tilde. Example: -wiki forum will find objects that do not contain wiki but contain forum

Grouping terms

Use parenthesis ( ) to group terms into subexpressions. Example: +wiki +(forum blog) will find objects that contain wiki and forum or that contain wiki and blog in any order.

Finding phrases

Use double quotes ( " " ) around a phrase to find terms in the exact order, exactly as typed. Example: "Alex Bell" will not find Bell Alex or Alex G. Bell.

Using wildcards

Add an asterisk ( * ) after a term to find objects that include the root word. For example, run* will find:

Reducing a term's value

Add a tilde ( ~ ) before a term to reduce its value indicate to the ranking of the results. Objects that contain the term will appear lower than other objects (unlike the minus sign which will completely exclude a term). Example: +wiki ~forum will rate an object with only wiki higher that an object with wiki and forum.

Changing relevance value

Add a less than ( < ) or greater than ( > ) sign before a term to change the term's contribution to the overall relevance value assigned to a object. Example: +wiki +(>forum < blog) will find objects that contain wiki and forum or wiki and blog in any order. wiki forum will be rated higher.
