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. ________________________________ >From : Jonathan Rochkind To : solr-user@lucene.apache.org; Subject : Re: previous and next rows of current record 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=1&start=$(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.
