RE: Re: previous and next rows of current record

  Yes exactly same problem i m facing. Is there any way to resolve this issue..

I am not sure what you mean, any way to resolve this issue. Did you read and 
understand what I wrote below? I have nothing more to add.  What is it you're 
looking for?

The way to provide that kind of next/previous is to write application code to 
do it. Although it's not easy to do cleanly a web app because of the 
sessionless architecture of the web. What are you using for your client 
application?  But honestly I probably have nothing more to say on the topic.

I think maybe I know what you mean.

You have a result set generated by a query. You have an item detail page
in your web app -- on that item detail page, you want to give
next/previous buttons for current search results.

If that's it, read on (although news isn't good), if that's not it,
ignore me.

There is no good way to do it. Although it's not really so much a solr
problem.  As far as Solr is concerned, if you know the query, and you
know the current row into the query i, then just ask Solr for
rows=1start=$(i=1) to get previous, or i+1 to get next. (You can't send
$(i-1) or $(i+1) to Solr that's just short hand, your app would have to
calculate em and send the literals).

The problem is architecting a web app so when you are on an item detail
page, the app knows what the current Solr query was, and what the i
index into it was.

The app I work on wants to provide this feature too, but I am so unhappy
with what it currently does (it is both ugly AND does not actually work
at all right on several very common cases), that I am definitely not
going to provide it as an example.  But if you are willing to have your
web app send the current search and the index in the URL to the item
detail page, that'd certainly make it easier.

It's not so much a Solr problem -- the answer in Solr is pretty clear.
Keep track of what index into your results you are on, and then just ask
for one previous or more.  But there's no great way to make a web app
taht actually does that without horrid urls.  There's nothing built into
Solr to help you. Solr is pretty much sessionless/stateless, it's got no
idea what the 'current' search for your particular session is.

 i.e. you still haven't answered the question about what 'next' and 'previous' 
 really means...

 But - if you already know that '9' is the next page, why not just do another 
 query with id '9' to get the next record?

 Hi

 in my case there is no id sequence. id is generated sequence wise for
 all category. but when we filter by category then same id become
 random. If i m on detail page which have id 5 and nrxt id is 9 so on
 same page my requirment is to get next id is 9.
