Hi,
      I create own field name using integer field type and sint field
type(solr.SortableIntField) in schema.xml.
i can't differentiate between these two field type. When this sint exactly
use? If we use sint how it is sortable? I test by {sort =field name} in
query window .but it's not work properly.please tell me with clear example
thanks in advance

In lucene, all the data is stored as strings, so if you have a field
defined as integer or sint, in lucene are strings, and if you try to
sort numbers represented as strings what happens is this:

example numbers: 1,2,3,4,5,6,7,8,9,10,11,12,13.
ordered as strings:    1,10,11,12,13,2,3,4,5,6,7,8,9

That's why there is a field type called sint, that means sortable int.
Is the same as int with the difference that it will order the numbers
properly.

example numbers: 1,2,3,4,5,6,7,8,9,10,11,12,13.
order being int:    1,10,11,12,13,2,3,4,5,6,7,8,9
order being sint:  1,2,3,4,5,6,7,8,9,10,11,12,13.

: as integer or sint, in lucene are strings, and if you try to sort numbers
: represented as strings what happens is this:

Field sorting in Solr on both IntField and SortableIntField should work
becuase they both use the 'integer' FieldCache under the covers -- but
where you'll really see a difference is in Range Queries (it's
admittedly a slightly confusing aspect of hte name, but it's spelled
out fairly well in the example schema.xml) ...

    <!-- numeric field types that store and index the text
         value verbatim (and hence don't support range queries, since the
         lexicographic ordering isn't equal to the numeric ordering) -->
    <fieldType name="integer" class="solr.IntField" omitNorms="true"/>
...
    <!-- Numeric field types that manipulate the value into
         a string value that isn't human-readable in its internal form,
         but with a lexicographic ordering the same as the numeric ordering,
         so that range queries work correctly. -->
    <fieldType name="sint" class="solr.SortableIntField" sortMissingLast="true" omitNorms="true"/>

can you elaborate on what exactly you have tried, and what you mean by
"it's not work properly" ?
