Rebuilds the search index. Reconstructs the index after changes to the
index schema, such as:
Adding or removing fields
Adding a copy field
Changing field settings
Queries using the solr_query option may return no results, partial
results, or old data while the index is rebuilding. You can verify an index's status by using
the dsetool core_indexing_status command. See Verifying indexing status.
Note: Perform index reloads or rebuilds on each Datacenter
(DC). It's only necessary to run the command on one node per DC. After modifying a search
index schema or coonfiguration, or uploading custom resources such as a synonym file, use
RELOAD SEARCH INDEX to reload and activate the search index. By default,
any uploaded resources are distributed across the cluster. For options to reload resources
on the current node only, see Reloading the search index.
Restriction: Command available only on DSE Search nodes.
Running search index management commands on large datasets can take longer than
the CQLSH default timeout of 10 minutes. Increase the CQLSH
client timeout as required.

Syntax conventions
Description
UPPERCASE
Literal keyword.
Lowercase
Not literal.
Italics
Variable value. Replace with a user-defined value.
[]
Optional. Square brackets ( [] ) surround
optional command arguments. Do not type the square brackets.
( )
Group. Parentheses ( ( ) ) identify a group to
choose from. Do not type the parentheses.
|
Or. A vertical bar ( | ) separates alternative
elements. Type any one of the elements. Do not type the vertical
bar.
...
Repeatable. An ellipsis ( ... ) indicates that
you can repeat the syntax element as often as required.
'Literal string'
Single quotation ( ' ) marks must surround
literal strings in CQL statements. Use single quotation marks to
preserve upper case.
{ key : value
}
Map collection. Braces ( { } ) enclose map
collections or key value pairs. A colon separates the key and the
value.
<datatype1,datatype2>
Set, list, map, or tuple. Angle brackets ( <
> ) enclose data types in a set, list, map, or tuple.
Separate the data types with a comma.
cql_statement;
End CQL statement. A semicolon ( ; ) terminates
all CQL statements.
[--]
Separate the command line options from the command arguments with
two hyphens ( -- ). This syntax is useful when
arguments might be mistaken for command line options.
' <schema> ... </schema>
'
Search CQL only: Single quotation marks ( ' )
surround an entire XML schema declaration.
@xml_entity='xml_entity_type'
Search CQL only: Identify the entity and literal value to
overwrite the XML element in the schema and solrConfig
files.
OPTIONS
The request option configures the entire request to specify whether to
delete the existing index:
deleteAll
true Completely replaces the existing index. Use when changes
to the schema affect the way that data is physically stored, such as changes to
the field type analyzer, a column data type, etc.
false (Default.) Keeps existing search index data. Reindexing
happens in-place; search results will return partially incorrect results while the
index is updating. Keep the current index (accepting reads) while you build the
new one, then swap over to the new index after it's ready. Use when table columns
are removed or added to the index.
