Dear Experts:
I am trying to measure the indexing and searching performance using a toy
benchmark and have few questions.
(1) Plan is to report the below metrics:
- Index creation: tokens/second
- Can I know how to obtain the tokens in the lucy_index created? Do
you think a better metric will be (Number of terms in the posting
list/second)? If so, how to obtain the number of terms in the
posting list?
- Search: free-text query/second
- Search metric is clean and clear since the toy benchmark controls the
number of queries.
(2) What are the different query types possible?
- vary document weighting
- Is it possible or is it fixed for a given lucy_index generated?
- vary number of terms
- vary relationship of terms (e.g., proximity)
- How to do it? Is there an operator like NEAR?
- vary operations (e.g., AND, OR)
- I see that the support is available for boolean query parser. Can I
know whether for a given search instance I can have multiple boolean
queries like below?
if (category) {
String *category_name = Str_newf("category");
String *category_str = Str_newf("%s", category);
TermQuery *category_query
= TermQuery_new(category_name, (Obj*)category_str);
Vector *children = Vec_new(2);
Vec_Push(children, (Obj*)query1);
Vec_Push(children, (Obj*)category_query);
query1 = (Query*)ANDQuery_new(children);
Vector *children = Vec_new(2);
Vec_Push(children, (Obj*)query2);
Vec_Push(children, (Obj*)category_query);
query2 = (Query*)ANDQuery_new(children);
DECREF(children);
DECREF(category_str);
DECREF(category_name);
}
Thanks
