I have two parallel multivauled fields for holding key value pairs for each
document.
<doc>
<arr name="value">
<str>red</str>
<str>other</str>
<str>VS</str>
<str>10 cm.</str>
<str>50 GB</str>
...
</arr>
<arr name="key">
<str>Color</str>
<str>Type</str>
<str>Brand</str>
<str>Size</str>
<str>RAM</str>
....
</arr>
</doc>
There ara about 300 different keys. New key values can be created dynamicly.
And some key values are meaningles for some documents. I want to faceting over
these multivalued fields. Something like:
RAM:
50 GB (5)
40 GB (2)
Brand:
XX (10)
VS (1)
color:
red (9)
blue (2)
Is there a way to create this kind of faceting over multi-valued fields?
And about querying multi-valued fields:
Lets say I want to get blue coloured documents,
The query '+key:color +value:blue' would return those two docs:
<doc1>
<arr name="value">
<str>blue</str>
...
</arr>
<arr name="key">
<str>color</str>
...
</arr>
</doc1>
<doc2>
<arr name="value">
<str>red</str>
<str>blue</str>
...
</arr>
<arr name="key">
<str>color</str>
<str>backcolor</str>
...
</arr>
</doc2>
Is there are way to get only doc1 for that kind of query?
Specifying/preserving index/position info for the multivalued fields.
Let's say I have a dynamic field defined as
<dynamicField name="*" type="string" >
and I add docs with the fields that are elements of those multivalued fields:
<add>
<doc>
<field name="color">blue</field>
<field name="brand">vs</field>
</doc>
</add>
Can I use those fields at query time, although they are not defined in
schema.xml?
'q=color:blue' and in faceting 'facet.field=color'
I'd appreciate any help and pointers.
