Conducting keyword searches in the Texas Digital Archive (TDA)

You can search the Texas Digital Archive (TDA) using simple keywords or phrases. When conducting a general search on the TDA, the TDA will search for terms within all parts of the file including the description of the file, the title of the file, and within the full-text of the file, when possible. Users should review the file description and the entire file or they may download and search the entire file to determine if the file is relevant to their research.

To do a search, enter the keyword into the search box at the top of the page (see Figure 1, below).


Figure 1.

In addition to entering keywords into the search box, you may also find it helpful to search using the two methods described below.
 

AND, OR, or NOT (Boolean) Searching

  • If you are looking for materials that have two keywords, type AND in capital letters between each keyword. This will narrow your search results to materials that have both terms (see Figure 2, below). For example: “Texas AND Mexico” will show results for materials that have both keywords Texas and Mexico.  It will not include materials that have results for only one of the terms.

  • Use OR in capital letters to include results that have one term or the other, but not both (see Figure 3, below). For example: “President OR Governor” will have results for either President or Governor.

  • Using NOT in capital letters will exclude results for a keyword. For example: if you wanted results for Houston, but didn’t want results for Sam Houston, you could use NOT to exclude results related to Sam Houston. Searching “Houston NOT Sam” will exclude “Sam” from the search (see Figure 4, below).

Please note that this type of searching works best when you only have two keywords, as demonstrated in the example above. If you have additional terms, you may want to use phrase searching instead, for example: Bexar NOT "San Antonio". Phrase searching is explained in greater detail below.

Phrase Searching

A phrase search is used to search a set of words in the exact order they appear. To do a phrase search, type quotation marks around the keyword phrase you wish to search for. For example: searching for the phrase “civil war” will return results for materials that have only that specific keyword phrase (see Figure 5, below).

Once you have completed your search, you may need to refine your results. Learn more about refining search results.

Searching within collections

To search all the collections in the TDA, enter your keyword or phrase into the search bar at the top of the page and click on the "Archive" button (see Figure 6, below).


Figure 6.

To conduct a keyword or phrase search within a collection, first navigate to the collection of interest to you. You may do so by browsing descriptive guides or using the Explore Archive feature. Then use the search bar located under the collection's description information (see Figures 7 and 8, below). The search button may say "collection" or "record" depending on what level of the collection you are viewing.


Figure 7. Search within "collection".


Figure 8. Search within "record".

Searching within a collection instead of across the TDA can be a useful strategy to narrow down your search results. For more tips, see refining search results.
