- Expression boosting
- Parenthetical grouping
Several types of terms are supported:
- Booleans
- Dates (absolute and relative, time points and ranges)
- Floats
- Integers
- IP Addresses
- Literal text
- Stemmed text
Specific terms can support the following features:
- Range queries (.lte/.lt/.gte/.gt)
- Fuzzing (~0.5)
- Wildcarding (*?)
- CIDR masks (/27)
The rich search expression grammar is arguably a defining feature of Philomena, and its

This allows the search engine to query the document.

become visible. Unless changed in the mapping, this happens after 5 seconds have elapsed.

Remove a single document from the index named by the module.

This undoes the effect of `index_document/2`; it instructs the search engine to discard
the document and no longer return it in queries.

be removed. Unless changed in the mapping, this happens after 5 seconds have elapsed.

Efficiently index a batch of documents in the index named by the module.
This function is substantially more efficient than running `index_document/2` for
each instance of a schema struct and can index with hundreds of times the throughput.
The queryable should be a schema type with its indexing preloads included in
the query. The options are forwarded to `PhilomenaQuery.Batch.record_batches/3`.

become visible. Unless changed in the mapping, this happens after 5 seconds have elapsed.

Asynchronously update all documents in the given index matching a query.
`POST /#{index_name}/_update_by_query`
This is used to replace values in documents on the fly without requiring a more-expensive
reindex operation from the database.
`set_replacements` are used to rename values in fields which are conceptually sets (arrays).
`replacements` are used to rename values in fields which are standalone terms.
Both `replacements` and `set_replacements` may be specified. Specifying neither will waste
the search engine's time evaluating the query and indexing the documents, so be sure to
specify at least one.
This function does not wait for completion of the update.
