Xpath expression for a custom SearchBoxEx WebPart to a DataFormWebPart

Question

Hi all,
I have a custom search webpart that has asp controls that are used in my dataview (DataFormWebPart) for retreiving data. This data view has the xslt variable "Rows" with the following xpath expression: 
<xsl:variable name="Rows" select="/dsQueryResponse/Rows/Row[
(contains(translate(@Title,'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz'), translate($FilterName,'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz')) or $FilterName = '')]"/>
*<ParameterBinding Name="FilterName" Location="Control(txtName)" DefaultValue=""/>
This webpart searchs for people by their name. For example:
search for:
jose
results:
jose luis escudero
jorge jose torres
Ok, it works fine there, but what if I want to search for: jose escudero. There won't be any results because the search xpath expressions has a contains function for what you write in the textbox control.
So I think it should be splited by " " and searchs for the each word in the @Title column of the data source.
I don't master xpath expressions so I don't know how to code a correct xpath expression for that, any idea? I would greatly appreciate any help. Thanks.

Hi  betozg31,
According to your description, the point is that your Xpath code put the “jose escudero” search keyword as a unitary string. So  your search  would not return any results. I think
if you want to search result using two or more keywords ,you need to deal with the keywords firstly. Separating from the “jose escudero” search keyword , getting “jose” search keyword and “escudero” search keyword. Here is a simple code you
can have a look:
<xsl:if test="$FilterName =' ' ">
<xsl:variable name="Rows" select="/dsQueryResponse/Rows/Row[ $FilterName=' ']"/>
</xsl:if>
<xsl:variable name="FormatFN" select="lower-case(normalize-space($FilterName))"/>
<xsl:variable name="FormatT" select="lower-case(@Title)" />
<xsl:if test="matches($FormatFN,' ')">
<xsl:variable name="FilterNameBefore" select="substring-before($FormatFN,' ')"/>
<xsl:variable name="FilterNameAfter" select="substring-after($FormatFN,' ')"/>
<xsl:variable name="Rows" select="/dsQueryResponse/Rows/Row[ contains(contains($FormatT, $FilterNameBefore),$FilterNameAfter )]"/>
</xsl:if>
<xsl:if test="not(matches($FormatFN,' '))">
<xsl:variable name="Rows" select="/dsQueryResponse/Rows/Row[ contains($FormatT,$FormatFN)]"/>
</xsl:if>
Hope this helps!
