Mongo Search

• MONGODB FULL TEXT SEARCH VS. REGULAR EXPRESSIONS

• mongoDB prefix wildcard: fulltext-search ($text) find part with search-string

Regex

db.books.find({title: /สวัสดี/i}, {title: 1}).pretty()

• Mongoose.js find with regex

• Mongo $regex

• Mongo $regex - Index Use

For case sensitive regular expression queries, if an index exists for the field, then MongoDB matches the regular expression against the values in the index, which can be faster than a collection scan.

For case insensitive regular expression queries, these queries generally cannot use indexes effectively.

Fulltext search

db.books.ensureIndex({title:"text"})
db.books.reIndex()
db.bokks.find({$text:{$search:"time"}})
