How to implement full-text search indexing with stemming and tokenization in Go?

To implement full-text search indexing with stemming and tokenization in Go, you can use the "bleve" library. Here is a step-by-step guide on how to do it:

  1. Install the "bleve" library by running the following command:

    go get github.com/blevesearch/bleve
  2. Create a new Go file and import the necessary packages:

    import ( "github.com/blevesearch/bleve" "github.com/blevesearch/bleve/analysis/analyzers/custom/analyzerstemmer" )
  3. Define a struct that represents your data structure:

    type Document struct { ID string Text string }
  4. Initialize the index and define the mapping for the field you want to search on (in this example, the "Text" field):

    mapping := bleve.NewIndexMapping() analyzer := analyzerstemmer.New("english") textFieldMapping := bleve.NewTextFieldMapping() textFieldMapping.Analyzer = analyzer mapping.AddCustomMapping(textFieldMapping, "Text") index, _ := bleve.NewMemOnly(mapping)
  5. Index your documents:

    doc1 := Document{ID: "1", Text: "The quick brown fox jumped over the lazy dog"} doc2 := Document{ID: "2", Text: "I have a cat named Whiskers"} index.Index(doc1.ID, doc1) index.Index(doc2.ID, doc2)
  6. Perform a full-text search on your indexed documents:

    query := bleve.NewQueryStringQuery("fox") searchRequest := bleve.NewSearchRequest(query) searchResult, _ := index.Search(searchRequest) for _, hit := range searchResult.Hits { fmt.Println(hit.ID, hit.Score) }

    This will output the ID and score of the documents that match the search query.

That's it! You have now implemented full-text search indexing with stemming and tokenization using the "bleve" library in Go.
