Besure to whitelist non-standard query parameters in your model.
That's ['$text', '$regex']
for MongoDB , and ['$where', '$regex']
for NeDB.
feathers-nedb-puzzy-search
take two options in NeDB $where
mode:
search({
fields: ['search.this.path', 'this.path.too', 'title'],
deep: true
})
fields
- Specify which fields to search.deep
- If true andfields
is undefined, will search deep in objects.
In NeDB $regex
mode it takes as service options the following:
excludeFields
- Specify which fields to exclude from search.fields
- Specify which fields to search. Mutually exclusive.
As query parameters it also takes $caseSensitive
