inputlookup command to search the contents of a lookup table. The lookup table can be a CSV lookup or a KV store lookup.
| inputlookup [append=<bool>] [start=<int>] [max=<int>] [<filename> | <tablename>] [WHERE <search-query>]
- Syntax: <string>
- Description: The name of the lookup file must end with
.csv.gz. If the lookup does not exist, a warning message is displayed (but no syntax error is generated).
- Syntax: <string>
- Description: The name of the lookup table as specified by a stanza name in the
transforms.conffile. The lookup table can be configured for any lookup type (CSV, external, or KV store).
- Syntax: append=<bool>
- Description: If set to
true, the data returned from the lookup file is appended to the current set of results rather than replacing it. Defaults to
- Syntax max=<int>
- Description: Specify the maximum number of events to be read from the file. Defaults to
- Syntax: start=<int>
- Description: Specify the 0-based offset of the first event to read. If
start=0, it begins with the first event. If
start=4, it begins with the fifth event. Defaults to 0.
- WHERE clause
- Syntax: WHERE <search-query>
- Description: Use this clause to improve search performance by prefiltering data returned from the lookup table. Supports a limited set of search query operators: =, !=, <, >, <=, >=, AND, OR, NOT. Any combination of these operators is permitted. Also supports wildcard string searches.
Generating commands use a leading pipe character and should be the first command in a search.
The lookup can be a file name that ends with
.csv.gz, or a lookup table configuration in the
Appending or replacing results
append=true, data from the lookup file or KV store collection is appended to the current set of results. By default,
append=false which means that the current result set is replaced with the results from the lookup search.
Working with large CSV lookup tables
The WHERE clause allows you to narrow the scope of the query that
inputlookup makes against the lookup table. It restricts
inputlookup to a smaller number of lookup table rows, which can improve search efficiency when you are working with significantly large lookup tables.

Example 1: Read in a
usertogroup lookup table that is defined in
| inputlookup usertogroup
Example 2: Read in a
usertogroup table that is defined by a stanza in
transforms.conf. Append the fields to any current results.
| inputlookup append=t usertogroup
Example 3: Search the
users.csv lookup file (under
| inputlookup users.csv
Example 4: Search the contents of the KV store collection
kvstorecoll that have a
CustID value greater than 500 and a
CustName value that begins with the letter P. The collection is referenced in a lookup table called
kvstorecoll_lookup. Provide a count of the events received from the table.
| inputlookup kvstorecoll_lookup where (CustID>500) AND (CustName="P*") | stats count
Example 5: View internal key ID values for the KV store collection
kvstorecoll, using the lookup table
kvstorecoll_lookup. The internal key ID is a unique identifier for each record in the collection. This requires usage of the
| inputlookup kvstorecoll_lookup | eval CustKey = _key | table CustKey, CustName, CustStreet, CustCity, CustState, CustZip
Example 6: Update field values for a single KV store collection record. This requires usage of
eval. The record is indicated by the its internal key ID (the
_key field) and this search updates the record with a new customer name and customer city. The record belongs to the KV store collection
kvstorecoll, which is accessed through the lookup table
| inputlookup kvstorecoll_lookup | search _key=544948df3ec32d7a4c1d9755 | eval CustName="Marge Simpson" | eval CustCity="Springfield" | outputlookup kvstorecoll_lookup append=True key_field=_key
Example 7: Write the contents of a CSV file to the KV store collection
kvstorecoll using the lookup table
kvstorecoll_lookup. This requires usage of both
| inputlookup customers.csv | outputlookup kvstorecoll_lookup
