Full pinyin spelling analyzer
Overview
The full pinyin spelling analyzer (full_pinyin) allows you to search for Chinese characters in short text by using full pinyin spellings or the first letter or the first couple of letters in abbreviated pinyin spellings. This analyzer is suitable for searches based on the full pinyin spelling or abbreviated pinyin spelling, such as searches for movie names or author names. To search for characters based on the full pinyin spelling, a user must enter the full pinyin spelling of the characters, not part of the full pinyin spelling.
To use the full pinyin spelling analyzer, set the analyzer to full_pinyin when you configure a schema. When you perform a query, set the analyzer for the corresponding index to pinyin_search_analyzer in the analyzer clause.
Example: If the value of a field is "大内密探007" in a document and the full pinyin spelling analyzer is specified, the document can be retrieved when a user searches for "d", "dn", "dnm", "dnmt", "dnmt007", "da", "danei", "daneimi", or "daneimitan". The document cannot be retrieved when a user searches for "an" or "anei".Abbreviated pinyin spelling analyzer
