Indexed Search
1.8.5. index_words, index_rel
Words-table and word-relation table. Almost self-explanatory. For the index_rel table some fields require explanation:
|
count |
Number of occurrences on the page |
|
first |
How close to the top (low number is better) |
|
freq |
Frequency (please see source for the calculations. This is converted from some floating point to an integer) |
|
flags |
Bits, which describes the weight of the words: 8th bit (128) = word found in title, 7th bit (64) = word found in keywords, 6th bit (32) = word found in description, Last 5 bits are not used yet, but if used they will enter the weight hierarchy. The result rows are ordered by this value if the "Weight/Frequency" sorting is selected. Thus results with a hit in the title, keywords or description are ranked higher in the result list. |
