[jira] [Commented] (S2GRAPH-209) GlobalIndex supports field data types such as Numeric to enable Range Query.

    [ https://issues.apache.org/jira/browse/S2GRAPH-209?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16447859#comment-16447859 ] 

Daewon Jeong commented on S2GRAPH-209:
--------------------------------------

The 'lucene' index provider is very difficult to implement range query, so it is left as a later implementation.


The implementation of the ragne query implementation in the 'elasticsearch' index provider is very easy and works well.

I will adjust the scope of the issue by applying 'elastic search' implementation and VertexQueryParam.

> h1. GlobalIndex supports field data types such as Numeric to enable Range Query.
> The provided GlobalIndex expects all stored fields as String values.
> For the above reason, even if the property type of the vertex/edge is Numeric, the following Range Query can not be performed.

> Change it to support it.
> The 'lucene' being implemented as a reference supports the field types listed below.
> {noformat}
>  {TextField}: {@link Reader} or {@link String} indexed for full-text search
>  {StringField}: {@link String} indexed verbatim as a single token
>  {IntPoint}: {@code int} indexed for exact/range queries.
>  {LongPoint}: {@code long} indexed for exact/range queries.
>  {FloatPoint}: {@code float} indexed for exact/range queries.
>  {DoublePoint}: {@code double} indexed for exact/range queries.
>  {SortedDocValuesField}: {@code byte[]} indexed column-wise for sorting/faceting
>  {SortedSetDocValuesField}: {@code SortedSet<byte[]>} indexed column-wise for sorting/faceting
>  {NumericDocValuesField}: {@code long} indexed column-wise for sorting/faceting
>  {SortedNumericDocValuesField}: {@code SortedSet<long>} indexed column-wise for sorting/faceting
>  {StoredField}: Stored-only value for retrieving in summary results
