Is it possible to make search within a field "Fuzzy" and yet "Boosted", but am running into two problems doing so. Is it possible to combine Fuzzy with Boost, and if so, how? I'm trying to do:
searchTerm.Fuzzy().Then().Boost(boostiness)
but am getting an ArgumentNullException on s. I also tried:
which solves the ArgumentNullException, but prevents Examine from returning results. The same thing happens if I use Boost and Fuzzy in the other order. I am probably doing something wrong, but am not sure what that would be.
at Examine.LuceneEngine.SearchCriteria.LuceneSearchExtensions.Then(IExamineValue examineValue, String s)
at Examine.LuceneEngine.SearchCriteria.LuceneSearchExtensions.Then(IExamineValue examineValue)
at ExamineTest.usercontrols.SearchResults.Page_Load(Object sender, EventArgs e)
The simplest case I could produce that generates the error is as follows:
or any of the variations of Boost/Fuzzy/Then chaining on SearchTerm that are shown in the original post.
I know I'm doing something wrong here but but I'm not sure what. nodeName is in the index and if no "fuzziness" is applied then it can be searched successfully.
I get this: Method not found: 'System.String Examine.LuceneEngine.SearchCriteria.LuceneSearchExtensions.Then(Examine.SearchCriteria.IExamineValue, System.String)'.
Been poking around under the hood - the "Then()" extension method has been commented out in recent releases. However, if you want to risk it you can actually just do this:
Examine - Combining Fuzzy with Boost

Any help would be appreciated.
Can you provide the full stack trace
The stack trace is as follows:
The simplest case I could produce that generates the error is as follows:
ISearchCriteria filter = criteria.Field("nodeName", SearchTerm.Boost(10.0f).Then().Fuzzy()).Compile();or any of the variations of Boost/Fuzzy/Then chaining on SearchTerm that are shown in the original post.

Thank you for looking into it.
Hi Chris,
Did you ever figure out what the problem was? I am in the same situation where combining SearchCriteria extensions, results in a exception.
Same here, 8 months later and still no one has bothered to answer the initial question.
I have been playing round with the following without getting any exceptions. Just looking at the quality of the results it pulls back
I get this:
Method not found: 'System.String Examine.LuceneEngine.SearchCriteria.LuceneSearchExtensions.Then(Examine.SearchCriteria.IExamineValue, System.String)'.
When I try this:
.Field("name", SearchName.Escape().Then(SearchName).Fuzzy())Been poking around under the hood - the "Then()" extension method has been commented out in recent releases. However, if you want to risk it you can actually just do this:
seeing as Fuzzy and Boost are string extensions, and you seem to be able to clump multiple IExamineValues together as strings.
is working on a reply...
