I have the following problem: in my application I'm trying to store set of keywords and their weights. Since the number of keywords is variable (and can be as high as 40) I decided to use a single field to store it. In other words, I want to use a single field with multiple values to store a keyword histogram of the document.
Now, I'm wondering how do I encode the weight of keywords... If I do the following:
Field f = Field.Keyword("kw", "value1");
f.setBoost(10.0);
doc.add(f);
f = Field.Keyword("kw", "value2");
f.setBoost(20.0);
doc.add(f);Now the question is: what is the boost value for the fields when I search? Is it equivalent to "value1^10.0 value2^20.0" (which is my intention), or rather "value1^20.0 value2^20.0"?
If the latter, do you have any suggestions how to achieve the original effect?
Thanks in advance!
