Here is a recap of what you can do in order to cross-search a specific term (artist, album title. etc.).
1) Label Search
Space for labels will contain only 200 characters per post, and blogger won't accept more than 20 labels per post in any case. This makes the usage of labels impractical for satisfactory name indexing. Thus, you will find posted as labels for any given post only the following:
1) Titular post artist.
3) Other musicians that appear as titular artists in already published posts, and who are playing on the same tracks as Lee.
In other words, should you want to find all the posts a specific labelled name was included in, you will have to click on the relative label at the bottom of any given post.
2) ‘Search This Blog’ function
Please use the ‘search this blog’ box on the right column of blog or in the navigation bar for names that fall outside the above labeling criteria (i.e. any musician/producer/technician who might have played a role in a project that did not bear their name).
3) External Google search
The ‘search this blog’ box will help you if you want to know in how many of these posts a certain name or title appears. Another option is to position yourself on an empty Google search page external of this blog and search for both blog and name/title together, putting the latter in between double quotes. For instance, to look for all of the Bass Routes entries that include both Leland Sklar and Carole King you should type:
site:bassroutes.blogspot.com “Carole King”
Once Google shows you the results go to last page, click on ‘repeat the search with the omitted results included’ at the bottom and you will now be able to sift through a complete list. Tipically, you will get the ‘real’ stuff first and then a series of spurious results appearing only because the search term was mentioned in comments and/or notes, or in monthly summaries, etc.
