| Description | resource summary | Easy Keyword Index This is a extention to the regular Keyword Index, which doesn't provide a NOT operator. Easy Keyword Index adds three operators, 'not', 'notor', and 'notand'. - 'not' and 'notor' are equivilent and first resolves any range operators, then make a union ('or') of the result, and at last inverts the result set so that all documentIds that are not in the Union are returned. - 'notand', first resolves any range operators, then intersects ('and') the results, and last inverts the result list. The Easy Keyword Index make one additional modification to the Keyword Index, namely it doesn't index documents (object) which doesn't have an attribute (of the same name as the index) or if that attribute returns None (either directly or the method returns None). This is (as often with my contributes) not a final product, merely a proposal of what should be in the ZCatalog core. Any comments may be sent to [email protected] and me [email protected] (I can mis any mail to [email protected] because I occational can be quite busy). Use Case The reason why I need this is because I am refactoring the ZBabel-product and need a way to return all messages that has not been translated yet. Because I have thrown out the SQL-parts of the original ZBabel product and replaced it with a ZCatalog I needed a possiblilty to index all translated languages and return any that didn't have the translated in that index. Combining the index with a generic tags-index I can get exactly those untranslated part of a web-site or Zope products that I like to translate. |
