lucene, or sql fulltext? - sql

Question

I want to create a search website to search docs (all kinds of formats including pdf), images, videos, and audio. I also want to be able to filter my search results based on some criteria like author name, date, etc.
I'm doing this in .NET, so what's the easiest way to get up and running? SQL fulltext searching seems tempting because I'm familiar with sql, and plus since I want to filter my search results, it will be easy to store the filter fields for each item.

Answer 1

If your primary concern is getting it up and running quickly and easily, then SQL fulltext search is definitely the way to go.
Lucene.NET has its advantages, but it is by no means a walk in the park to set up correctly. The documentation is a bit lacking and there are a very limited number of examples on the web.

Stored procedure for snippets:
CREATE PROCEDURE SimpleCommentar
#SearchTerm nvarchar(100),
#Style nvarchar(200)
AS
BEGIN
CREATE TABLE #match_docs
(
doc_id bigint NOT NULL PRIMA
);
INSERT INTO #match_docs
(
doc_id
)
SELECT DISTINCT
Commentary_ID
FROM Commentary
WHERE FREETEXT
(
Commentary,
#SearchTerm,
LANGUAGE N'English'
);
DECLARE #db_id int = DB_ID(),
#table_id int = OBJECT_ID(N'
#column_id int =
(
SELECT
column_id
FROM sys.columns
WHERE object_id = OBJECT_I
AND name = N'Commentary'
);
SELECT
s.Commentary_ID,
t.Title,
MIN
(
N'...' + SUBSTRING
(
REPLACE
(
c.Commentary,
s.Display_Term,
N'<span style="' + #Style + '">' + s.Display_Term + '</span>'
),
s.Pos - 512,
s.Length + 1024
) + N'...'
) AS Snippet
FROM
(
SELECT DISTINCT
c.Commentary_ID,
w.Display_Term,
PATINDEX
(
N'%[^a-z]' + w.Display_Term + N'[^a-z]%',
c.Commentary
) AS Pos,
LEN(w.Display_Term) AS Length
FROM sys.dm_fts_index_keywords_by_document
(
#db_id,
#table_id
) w
INNER JOIN dbo.Commentary c
ON w.document_id = c.Commentary_ID
WHERE w.column_id = #column_id
AND EXISTS
(
SELECT 1
FROM #match_docs m
WHERE m.doc_id = w.document_id
)
AND EXISTS
(
SELECT 1
FROM sys.dm_fts_parser
(
N'FORMSOF(FREETEXT, "' + #SearchTerm + N'")',

WHERE p.Display_Term = w.Display_Term

) s
INNER JOIN dbo.Commentary c

INNER JOIN dbo.Book_Commentary bc
