In-place updates are very similar to atomic updates; in some sense, this is a subset of atomic updates. In regular atomic updates, the entire document is re-indexed internally during the application of the update. However, in this approach, only the fields to be updated are affected and the rest of the documents are not re-indexed internally.

Hence, the efficiency of updating in-place is unaffected by the size of the documents that are updated i. Apart from these internal differences, there is no functional difference between atomic updates and in-place updates.

An atomic update operation is performed using this approach only when the fields to be updated meet these three conditions:. To use in-place updates, add a modifier to the field that needs to be updated. The content can be updated or incrementally increased. A client reads a document. Specific semantics are used to define when the document should be updated or when to report a conflict. In this case, no version matching occurs, but if the document does not exist, the updates will be rejected.

In this case, no version matching occurs, but if the document exists, the updates will be rejected. If it exists, it will be overwritten; if it does not exist, it will be added. The JSON update format allows for a simple delete-by-id. For example, a single document:. Solr can support custom JSON.

Character used as field separator; default is ",". This parameter is global; for per-field usage, see the split parameter. If true , remove leading and trailing whitespace from values. The default is false.

This parameter can be either global or per-field. Number of lines to discard in the input stream before the CSV data starts, including the header, if present. This parameter is global. The character optionally used to surround values to preserve characters such as the CSV separator or whitespace. This standard CSV format handles the encapsulator itself appearing in an encapsulated value by doubling the encapsulator.

The character used for escaping CSV separators or other reserved characters. If an escape is specified, the encapsulator is not used unless also explicitly specified since most formats use either encapsulation or escaping, not both.

Keep and index zero length empty fields. If you specify multiple ids, or use the ids parameter, the response will mimic a normal query response to make it easier for existing clients to parse. Real Time Get requests can also be combined with filter queries, specified with an fq parameter :.
