Saving Your Search

Doing a careful PubMed search can take some time. You may want to save what you have been doing halfway through or you may want to be able to repeat the search later. There are a number of ways you can do this

  • Using the PubMed Cubby facility (from cubbyhole I presume)
  • Store your search string
  • Store the URL or use it as a link

Unfortunately all of these approaches have a common problem. If you have a really complicated search and you have used the history function to make it seem simpler non of these approaches to storing the search will work. You can only store a string with the number in it and this number will be no good within 1 hour of you stopping the search. So you have to reconstruct your search into a great long string for any of the storage schemes to work.

I am interested in the apparent fact that patients who have a sequential contralateral hip fracture very often have exactly the same fracture pattern.

I performed a search for "bilateral intertrochanteric fractures" and obtained a list which obviously needs a lot of work. I will come back to it later but want to store the search strategy as a starting point. sav2.gif (7282 bytes)

Cubby

This is a PubMed facility with many useful features.

After you have run the search you want to save click on the link to Cubby under PubMed Services to the left of the screen

Cubby requires that you register and that your system accepts cookies. Registration is free. If you don't know anything about cookies your system probably does accept them (they are small files which the site attaches to your system to follow where you go).

If you haven't already registered click on the link to go through the registration process. Otherwise Login

Unless you have been here before you will be told that nothing is currently stored. However, if you want to store the current search you can re-name it by editing the "Cubby Search Name" in the text box and then store it by clicking on the button sav4.gif (2847 bytes)

The page shows that you have saved one search called bilateral intertrochanteric fractures. If you were to select it by clicking on the #1 checkbox, then clicking on "What's New for Selected" (arrow) the facility would provide all the articles that had been published since the last time you searched. This would be extremely helpful for keeping up with the literature on a specific topic. Since you have only just stored it there is no point in doing this now.

Suppose you want to come back to this search project. Access the Cubby site and click on the Search Name link sav6.gif (2527 bytes)
The page will display the basic information about the search including the search string

To do the search click on the button

Clicking on the Details link shows that PubMed has translated the search string to include all hip fractures sav7.gif (3493 bytes)
However, editing the search string thus doesn't help at all

sav8.gif (2777 bytes)

Somewhat later I realized that "Bilateral" was not really what I meant and tried a search for "sequential" hip fractures. This seems more likely to be useful so I am going to store that instead of the "bilateral search"

Click on the link to Cubby again and Edit the Search Name to something appropriate. Click on Store in Cubby sav11.gif (3066 bytes)
To delete the previous useless search click on the checkbox for the search (#1) then click on Delete Selected Searches sav12.gif (4426 bytes)
The Sequential Hip Fracture search is now stored. sav13.gif (5556 bytes)

Storing the search string

In some respects this is the easiest thing to do if you are comfortable creating and finding files in your computer. You may need to create a folder in My Documents and call it PubMed_Searches. If you don't know how to do that, this is not a good plan for you!

From the PubMed page click on Details and select all the text in the PubMed Query Box. sav14.gif (3857 bytes)

Copy the text to "Clipboard" (Control C)

Open a Word Processing file (Notebook will be fine) and paste the contents of the clipboard to this file. (Control V).

Save the file in PubMed_Searches as a text file. Make sure the name of the file is something you will associate with the search subject. Alternatively you can have one file and add search strings to it, with appropriate introduction.

Later when you need to do the search again you can open the file and copy and paste the search string to the PubMed entry box.

If this is all new to you, this is not the best way to do this; use Cubby instead.

Unfortunately, if you have used the history facility this will not work as the history is not carried over from one session ot the next.


Storing the URL

The URL is the Universal Resource Locator, or address on the Internet. PubMed addresses are very complex as the pages are created on-the-fly by the search engine. The information on how to create the pages has to be included in the URL. So if the search string gets complicated, the URL looks super-complicated. Fortunately you don't have to remember it, interpret it or type it out. All you need to do is store it and transcribe it accurately.

This is the URL for the sequential intertrochanteric fractures search (it won't bite :-)

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=PureSearch&db=PubMed&
details_term=%28sequential%5BAll%20Fields%5D%20AND%20%28%22
hip%20fractures%22%5BMeSH%20Terms%5D%20OR%20intertrochanteric%20
fractures%5BText%20Word%5D%29%29

If you know how to do it, it is much better to store this URL as a link. The same information is in the link Search for Sequential IT Fractures but is decently concealed!

PubMed makes you do an extra step to find and copy the URL.

After you have done a search open the Details page

Click on the URL button

sav15.gif (4673 bytes)

The search is repeated but the URL for the search appears in the Address line of your browser.

sav21.gif (2565 bytes)

Click on it once to select the whole line, even the parts you cannot see. Press Control C to copy it to the clipboard. Open a file and paste it to it just like you did for the search string.

If you want to go for broke and make a link it is not difficult if you have an up to date version of MS Word. Note that the URL is still stored on the clipboard.

 

Open a Word file

Type a description of the search - eg PubMed Search for Sequential Hip Fractures

Select some or all of the title

Click on the Insert Hyperlink Icon

sav17.gif (7579 bytes)
The dialog box to insert a link is opened Note that the space for the URL is blank

sav18.gif (8936 bytes)

Paste the URL from the clipboard into the box by pressing Control V

Confirm that the URL has been pasted and click OK

sav19.gif (8774 bytes)
The text selected is now a link to the PubMed address, as you can confirm by placing the cursor over it

sav20.gif (6001 bytes)

This also will not be satisfactory if you have been using the history function to describe your search. The URL will contain directions to the history which won't be there next time.

Summary

  • The Cubby facility at PubMed is a convenient way to save your searches. It can also be used to show you what's new for a particular search.
  • You can copy and store the search string as text, or extract the URL and save that as text or a link.
  • None of these strategies work if there is a reference to a history number in your search string. That number will be meaningless next time you log on.
