Examine Lucene RawQuery boost create date
Hi,

I'm trying to sort my search results so that items with the latest date will have a higher Lucene score and show up at the top of the results. This is my raw query at the moment, which I edited from https://umbraco.com/blog/examining-examine/
```
var luceneString = "nodeName:";
luceneString += "(+" + searchTerm.Replace(" ", " +") + ")^10 ";
luceneString += "nodeName:" + searchTerm + "~0.8";
luceneString += " bodytext:" + searchTerm + "~0.8";
```
Does anyone know how to include a boost on createDate please?

Thanks!

Angel,

Why not just sort by date? In this instance unless you are searching by date i do not see how you can boost it?

Ismail

Hi Ismail,

Thank you for your reply. I want to sort by relevance then by date and this doesn't seem to be working:
```
var searchResults = searcher.Search(query).OrderByDescending(x => x.Score).ThenBy(r => r.Fields["createDate"]);
```
If there is no way to boost the date then does anybody know why the above isn't working?

Thanks, Angel

sorry for opening an old thread...

by doing the above, you sort outside examine. You need to add the sorting to your query :)

Angel,

Once you sort by any field then score has no meaning. In fact after a sort if you write out the score you should get NAN as its no longer relevant.

Mohsin,

Ideally you should have created new post and not added to existing post which is different topic. However it may be your external index is corrupt. So goto developer section examine management indexers / external index and rebuild. Then try and delete your media item.

Ismail
