Note: This node is not actively maintained or supported any longer.

The “Web Searcher” node can query a number of different web search engines and delivers the search results. Currently, the node supports Bing, Blekko, DuckDuckGo, Google, Hakia, Twitter, Yandex, YouTube, and more. The following search engines require an API key; use the links to obtain such a key:

Flickr, Google Custom Search, Instagram, Twitter, Vimeo, Yandex, YouTube.

Options

Query input
The column in the input table providing the queries.
Search engine
The search engine to query.
Number of results
The number of desired results per query. If the search engine does not provide as many results as specified (which might also be the case due to API restrictions), less than the specified number of results might be provided.
Append total result count column
If activated, an additional column is appended to the result table, which contains the number of total results the searcher found for the given query. Note, that this functionality is not supported for every searcher (in this case, a missing value will be appended), or sometimes the value might just be a more or less rough estimate.
Language
The language to search for.

Input Ports

Icon
A table with a list of query terms. You may use the specific search engine’s operators (boolean, quotes, etc.) for the query.

Output Ports

Icon
A table with the results of the search, containing the original query term, the title, summary, URL and (if provided) date and geographic coordinates of the result. In case, videos or images were searched, additional columns with image-/video-specific properties are appended.
