wordsList (WordCollection): WordCollection of Word objects, with inBody, in Title, inURL fields filled

Remarks

This method defines the relationship between the occurrences (hits) in the document and the weight of the words in the document. Eg. A document contains 4 words; "this", "is", "this", "example". The document's title is; "example" The document's URL is; http://localhost/example.html If phrase matching is enabled, when the build is performed the wordsList parameter will contain Word objects with the following data:

	Copy
wordsList[0] = "this", inUri=0, inTitle=0, inBody=1 wordsList[1] = "is", inUri=0, inTitle=0, inBody=1 wordsList[2] = "this", inUri=0, inTitle=0, inBody=1 wordsList[3] = "example", inUri=1, inTitle=1, inBody=1

Copy

wordsList[0] = "this", inUri=0, inTitle=0, inBody=1
wordsList[1] = "is",   inUri=0, inTitle=0, inBody=1
wordsList[2] = "this", inUri=0, inTitle=0, inBody=1
wordsList[3] = "example", inUri=1, inTitle=1, inBody=1

If phrase matching is disabled, when the build is performed the wordsList parameter will contain Word objects with the following data:

	Copy
wordsList[0] = "this", inUri=0, inTitle=0, inBody=2 wordsList[1] = "is", inUri=0, inTitle=0, inBody=1 wordsList[2] = "example", inUri=1, inTitle=1, inBody=1

This method is then called to calculate the Weight property in the Word objects (by default it uses the weight coefficients). This method can therefore be overridden with custom rules for weighting.
