We use the
Umbraco Full Text Search package which is a great tool for simple full text site wide searching. It does however use a XSLT macro to render its search results. We have an extensive collection of Razor Macros and as such I wanted a Razor version of this package to simplify development. One does not exist So i took the time to convert the XSLT macro into a Razor macro included below. Just add it to you MacroScripts folder and then change the FullTextSearch Macro to use this instead of the original version. The output should be identical to the XSLT version.

Full Text Search
V0.25
======================================================================
This XSLT file sets up queries and sends them off to FullTextSearch's
XSLT helpers.
Feel free to modify any part of it to your own needs. HTML is near
the bottom in a couple of templates.
PARAMETERS:
queryType
Type of search to perform. Possible values are:
MultiRelevance ->
The default.
The index is searched for, in order of decreasing relevance
1) the exact phrase entered in any of the title properties
2) any of the terms entered in any of the title properties
3) a fuzzy match for any of the terms entered in any of the title properties
4) the exact phrase entered in any of the body properties
5) any of the terms entered in any of the body properties
6) a fuzzy match for any of the terms entered in any of the body properties
MultiAnd ->
Similar to MultiRelevance, but requires all terms be present
SimpleOr->
Similar to MultiRelevance again, but the exact phrase does not
get boosted, we just search for any term
AsEntered->
Search for the exact phrase entered, if more than one term is present
______________________________________________________________________
titleProperties
A comma separated list of properties that are part of the page title,
these will have their relevance boosted by a factor of 10
defaults to nodeName. Set to "ignore" not to search titles.
______________________________________________________________________
bodyProperties
A comma separtated list of properties that are part of the page body.
These properties and the titleProperties will be searched.
defaults to using the full text index only
______________________________________________________________________
summaryProperties
The list of properties, comma separated, in order of preference,
that you wish to use to create the summary to appear under
the title. All properties selected must be in the index, cos that's
where we pull the data from.
Defaults to Full Text
______________________________________________________________________
titleLinkProperties
The list of properties, comma separated, in order of preference,that you
wish to use to create the title link for each search result.
Defaults to titleProperties, or if that isn't set nodeName
______________________________________________________________________
rootNodes
Comma separated list of root node ids
Only nodes which have one of these nodes as a parent will be returned.
Default is to search all nodes
______________________________________________________________________
contextHighlighting
Set this to false to disable context highlighting
in the summary/title. You may wish to do this if you are having
performance issues as context highlighting is (relatively)
slow.
Defaults to on.
______________________________________________________________________
summaryLength
The maximum number of characters to show in the summary.
Defaults to 300
______________________________________________________________________
pageLength
Number of results on a page. Defaults to 20. Set to zero to disable paging.
______________________________________________________________________
fuzzyness
Lucene Queries can be "fuzzy" or exact.
A fuzzy query will match close variations of the search terms, such as
plurals etc. This sets how close the search term must be to a term in
the index. Values from zero to one. 1.0 = exact matching.
Note that fuzzy matching is slow compared to exact or even wildcard
matching, if you're having performance issues this is the first thing
to switch off.
Defaults to 0.8
______________________________________________________________________
useWildcards
Add a wildcard "*" to the end of every search term to make it match
anything starting with the search term. This is a slightly faster, but
less accurate way of achieving the same ends as fuzzy matching.
Note that fuzzyness is automatically set to 1.0 if a wildcards are enabled.
Defaults to off
