Hello,

I have some questions about the query behavior

I created a collection food and put the following documents into it.

<food type="snack">
        <dish num="1">apple</dish>
        <dish num="2">snickers</dish>
        <dish num="3">crackers</dish>
        <dish num="4">carrots</dish>
</food>
<food type="lunch">
        <dish num="1">spagetti</dish>
        <dish num="2">steak</dish>
        <dish num="3">macroni and cheese</dish>
        <dish num="4">stir fry</dish>
</food>
<food type="breakfast">
        <dish num="1">Toast</dish>
        <dish num="2">Omelet </dish>
        <dish num="3">Cereal</dish>
        <dish num="4">Bagel</dish>
</food>
<food type="lunch">
        <dish num="1">sandwich</dish>
        <dish num="2">pho</dish>
        <dish num="3">pizza</dish>
        <dish num="4">leftovers</dish>
</food>

if I use the following query I get the expected result:

xindice xpath_query -c /db/food -q"/[EMAIL PROTECTED]'snack']"
trying to register database

<food src:col="/db/food" src:key="food4.xml" type="snack"
xmlns:src="http://xml.apache.org/xindice/Query";>
        <dish num="1">apple</dish>
        <dish num="2">snickers</dish>
        <dish num="3">crackers</dish>
        <dish num="4">carrots</dish>
</food>

if I do the following query I get the expected results.

C:\Documents and Settings\peter>xindice xpath_query -c /db/food -q
"/food/[EMAIL PROTECTED]'2']"

trying to register database
<dish num="2" src:col="/db/food" src:key="food1.xml"
xmlns:src="http://xml.apache.org/xindice/Query";>pho</dish>
<dish num="2" src:col="/db/food" src:key="food2.xml"
xmlns:src="http://xml.apache.org/xindice/Query";>Omelet </dish>
<dish num="2" src:col="/db/food" src:key="food3.xml"
xmlns:src="http://xml.apache.org/xindice/Query";>steak</dish>
<dish num="2" src:col="/db/food" src:key="food4.xml"
xmlns:src="http://xml.apache.org/xindice/Query";>snickers</dish>

but if I do the following query:

xindice xpath_query -c /db/food -q "/food/dish/.='pho'"

trying to register database
<xq:result
xmlns:xq="http://xml.apache.org/xindice/Query";>true</xq:result>
<xq:result
xmlns:xq="http://xml.apache.org/xindice/Query";>false</xq:result>
<xq:result
xmlns:xq="http://xml.apache.org/xindice/Query";>false</xq:result>
<xq:result
xmlns:xq="http://xml.apache.org/xindice/Query";>false</xq:result>

I get a result that tells me that there is a <dish>pho</dish> in my
collection, but gives me no information about what document it is in,
which seems strange.

I understand the different nature of these XPath expressions, however
the query seem a natural one, but the result is not particularly useful.

Is this just a limitation of the command line tool?

I'm going to start working with the API now :)
