Issue with Lucene Field query with 'No' value

albergquist — Thu, 14 May 2009 20:23:03 GMT

In Alfresco 2.1 and 3.1, the Lucene search does not return content on a field search where the property value is 'No', 'no' or 'NO'. For example, the query below does not return any results when I have content with Author specified as "No". This same query works correctly for other author value

Lucene tokenizes and manipulates content before it places it inside the index. Most likely, the author "No" will not be present in the indices. You could try turning tokenization off for the given field in the Contentmodel.

Thank you so much for your reply– that was the issue.

For those also experiencing this, please note the following stop words in Lucene Analyzer – these will be removed during tokenization:
"a", "an", "and", "are", "as", "at", "be", "but", "by","for", "if", "in", "into", "is", "it", "no", "not", "of", "on", "or", "s", "such", "t", "that", "the", "their", "then", "there", "these","they", "this", "to", "was", "will", "with"

Please note that "s" and "t" are no longer stop words in Lucene 2.2; however Alfresco 2.1-3.1 use Lucene 2.1.

If I search "rocket science", I found 40 records (even search "department rocket science", got the same results), I only got one result if I search "department of rocket science". But actually 40 records all have "department of rocket science" precisely but the one result including two "of" stop words like "department of rocket science, office of blah blah". Can someone explains what wrong?

Thanks
