Hi Everyone,

I am currently in process of upgrading Ferret 0…9.1 to Ferret 0.10.9  
with Ruby 1.8.4 in windows platform. I am trying to use search highlight  
feature on index\_searcher

```
subject = index_searcher.highlight("subject:(blah blah)", 0,
                             :field => :content,
                             :pre_tag = "<span class='highlight'>",

```

:post\_tag = “”)

But all my tests fails and I run into Segmentation Fault Error.  
Does anyone has come across this bug? I see couple of emails in this  
forum but  
I have not been able to find solutions. Can some one please help me and  
tell me what is the correct implementation ?

-Amit

It looks like you are using IndexSearcher#highlight. The first  
argument must be a Query object rather than a String. If you want to  
use a String then you should use Index#highlight.

Hope that helps.
