Following are the access point to search on Books and Thesis database of KOHA.
To search the OPAC you can either choose to enter your search words in the box at the top of the OPAC or click on the ‘Advanced search’ link to perform a more detailed search.
When you can’t find the most appropriate material with a general search, you can move to the Advanced Search page by clicking on the Search option on the persistent toolbar.
The Advanced Search page offers many ways to limit the results of your search. You can search using the Boolean operators AND, OR, and NOT; limit by item type; limit by year and language; limit by subtypes audience, content, format, or additional content types; by location and by availability.
In this section you can choose among the many indexes by clicking on the arrow in the first box. The blank box that follows is where you enter your first search term or terms. On the second line, you can choose the Boolean operator you want to use in your search. The options are ‘and’, ‘or’, and ‘not’. Then, you would again choose the index to search, followed by the second term or terms. If you have more concepts you want to include in your search, you can click the [+] to add another line for your search.
A sample search is shown next, followed by its results:
When you use the Boolean operators to broaden or narrow a search, remember the action of each operator. The ‘and’ operator narrows the results you’ll retrieve because the search will retrieve the records that include all your search terms. The ‘or’ operator expands the results because the search will look for occurrences of all of your search terms. The ‘not’ operator excludes records with the term that follows the operator.
Note: If you leave this expandedSearchOption set to ‘don’t show’, this is the display you will see:
The Advanced Search page then shows the multiple kinds of limits that can be applied to your search results. Either check a box or select from the drop down menus to narrow your search. You will type the year, year range, or a ‘greater than (>)’ or ‘less than (<)’ year.
