When you are there, you can click on the little magnifying glass icon to search for individual records. You can click on the camera icon to view the images. Those icons look like the images below:
Now, the search function and images are not synchronized. Therefore, you can't click from the search results to see the images. However, there is a way to find the records you want. First, search for the name, such as what I did here with Maria Clara Torres. Notice it says "No image available". Notice that the Christening Date is 15 Sep 1826.
Since the records for this collection begin in 1821, I can assume that the record will be early on. Therefore, I will search the first few images. If I were looking for a record in the 1840s, I would search further into the collection. You will need to be able to read dates in Spanish to find the date you are looking for.
I was able to find Maria Clara's baptismal record on image #47. Notice that it has her name in the left hand margin of the page.
A closer view of the record shows the date "el dia quince del mes de Setiembre (sic) de mil ochocientos viente y seis", or in English "the 15th day of September 1826". If you don't read Spanish, you can learn it easily enough. Beginning Spanish textbooks often start with numbers and dates, and there are probably instructional websites online.
