Methods
selectWebSearchRank
Add a column with a rank/score for the given query.
The column alias defaults to rank
.
The rank/score is calculated using the Postgres function ts_rank
.
const results = await db('products')
.select('id', 'name')
.selectWebSearchRank('description', 'Shoes')
.whereWebSearch('description', 'Shoes')
.orderBy('rank', 'desc');
whereWebSearch
Add a WHERE
clause to your query to filter by the given query.
Used in conjunction with selectWebSearchRank
to compute a rank
to order the results.
Note: Intelligently handles undefined
input by returning the query builder unmodified.
const results = await db('products')
.select('id', 'name')
.selectWebSearchRank('description', 'Shoes')
.whereWebSearch('description', 'Shoes')
.orderBy('rank', 'desc');
