Lunr-core is a small, full text search library for use in small applications.
It's a port of lunr.js to .NET Core. Lunr is a bit like Solr, but much smaller and not as bright.
A very simple search index can be created using the following:
var index = await Index.Build(async builder =>
{
builder
.AddField("title")
.AddField("body");
await builder.Add(new Document
{
{ "title", "Twelfth-Night" },
{ "body", "If music be the food of love, play on: Give me excess of it…" },
{ "author", "William Shakespeare" },
{ "id", "1" },
});
});
Then searching is as simple as:
await foreach (Result result in index.Search("love"))
{
// do something with that result
}
This returns a list of matching documents with a score of how closely they match, the search query as well as any associated metadata about the match:
new List<Result>
{
new Result(
documentReference: "1",
score: 0.3535533905932737,
matchData: new MatchData(
term: "love",
field: "body"
)
)
}
Lunr-core is a small, full-text search library for use in small applications. It indexes documents and provides a simple search interface for retrieving documents that best match text queries. It is 100% compatible with lunr.js, meaning that an index file prepared on the server with lunr-core can be used on the client using lunr.js.
Lunr-core is suitable for small applications that require a simple search engine but without the overhead of a full-scale search engine such as Lucene. Its compatibility with lunr.js also opens up some interesting client-side search scenarios.
