Amazon Elasticsearch Service adds support for hot reload of dictionary files
Amazon Elasticsearch Service now supports the ability to reload dictionary files without reindexing your data. Elasticsearch uses analyzers to convert string data into terms or tokens that power its search capabilities. These analyzers can do things like remove white space and stop words, perform stemming, handle compound words, and add synonyms. Previously, on Amazon Elasticsearch Service these analyzers could only process data as it was indexed. If you wanted to add some additional synonyms at a later time, you had to reindex your data with the new dictionary file.
