PubCrawler Orientation Help: Query Options
Entering PubCrawler Configurator (either directly or through WWW-PubCrawler's 'Modification of Queries & Options') allows you to add, delete, modify and check queries for PubCrawler's configuration file.
The following sections will explain how to proceed:
- add a query:
Make the following entries either for queries at GenBank or PubMed:
When done, click on 'Submit'.
- Replace the alias string (optional) in the green field - this should be a short descriptive term for your query.
- Type a search term into the long yellow field.
- Choose a search field from the blue menue.
Tip: For general info on query specification check out NCBI's PubMed Help and PubMed FAQ.
- Proceed in the same manner for up to five search terms.
(if you need more entry boxes, click on 'Submit' and then choose to 'Modify' that query)
- Choose the desired boolean operator to combine two or more search terms.
- delete a query:
Each query that you have setup is followed by a check-box which will mark deletion of that query if activated.
To delete a query simply click an the according check-box and press the 'Submit' button.
- modify a query:
Each query that you have setup is followed by a Modify <database># button (database can be either PubMed or GenBank, # stands for the number of the query). If you click on that the according query will be split up into its components and presented in the entry boxes. Two more empty boxes will be provided for extension of the query.
After modifying the data, click on 'Submit' and see the changed query appear at the bottom of your query list.
This can also be used to change the order of your queries.
- check a query:
You might be wondering, how specific your query is and if you can expect any hits at all.
This can be easily answered by checking a query directly at NCBI's Entrez (where the actual PubCrawler run will be carried out). Just specify how far back you want to search (default: entries of the last 90 days) and click on 'Check PubMed #' or 'Check GenBank #', depending on which database you are accessing (# stands for the number of the query). After a moment (depending on network traffic and server load) you will get the number of hits for your query together with links for up to 60 example reports. If no documents are reported try to extend the time range and keep it in mind for the setting of your PubCrawler options. If you get lots of hits, take a look at the results and try to further specify your query.
