Below are a list of frequently asked questions which FALSC has compiled on the features of Mango.
Q. How does Mango's "relevance" feature work?
A. Mango uses the Lucene scoring algorithm, Lucene Scoring Model, also known as the tf.idf model. This scoring model
involves a number of scoring factors:
Additionally, a special “case” was added for titles containing less than five words. An index term is added for titles with less than 5 words so that they will rise to the top of the search results. These additional indexes don’t take the filing indicator into account.
Q. What is the new URL to the upload/download page that was used by the universities in Aleph version 20?
A. The new upload/download page used by the universities is https://susopac.falsc.org/S
Q: Why are my call numbers not showing up in Mango?
A: The first indicator of the 852 field must include a value, such as 0 (LC Call numbers).
Q: What are the stop words (words that can't be searched) in Mango?
A: a, an, and, or, the, el, la, las, los, du
Q: Why does the pagination on an "All" type of search only indicate Page 1 and Next, but not the list of pages by number as on other types of searches?
A: The difference in paging of search results is based on whether search results come from a single source or multiple sources. If a search result is from a single source, Mango is able to create links for paging through the result set, including jumping ahead more than one page. For the All tab or pre-filter dropdown search option, the search results come from multiple sources that are blended together. Mango keeps track of how the results are blended for the current page it is displaying. Previous and next is possible, but jumping ahead more than one page is not possible at this time.
Q: Can we get the Boolean operators to appear on each of the three versions of the Advanced Search (Books and Articles, Books and More, Articles and More)?
A: The Primo Central Index does not use Boolean operators for searches. Therefore, the Boolean operators go away for a search involving articles. EBSCO appears to use Boolean operators when the EDS mega-index is searched and we should be able to retain the option for search types involving content coming from the mega-index.
Q: When is it possible to use the multi-select option to select more than one of the choices under each facet category?
A: Multi-selection of facets is only available in a “Books & More” (library catalog) search.
Q: Is it possible to add a limiter to the keyword list that is to search by barcode?
A: Barcode is not currently searchable in Mango
Q: How does Mango display holdings information on the detailed record page, in particular when we have the same title with different volumes (ranges of years) in two different locations?
A: The Mango display sorts this way: bib number, adm number, hol number, sublibrary code, collection code with the smaller numbers on top. This is a system-wide setting and can’t be changed.
Q: What do I do if the book jacket image is wrong?
A: FALSC uses Google Books to supply the book jackets and other information about the book. If you notice a problem, contact the FLVC Help Desk and we'll report it to Google.
Q: What do I do if I find a print book that displays as an ebook or an ebook that displays as a print book?
A: Report these to the FLVC Help Desk. FLVC staff will investigate and correct the record(s). Occasionally there are errors. For example, if a record with an 856 has a blank or a 0 in the 2nd indicator, Mango treats it as an ebook. Changing the 2nd indicator to 2 should result in the record showing up as a print book after the bib data refresh.
Q: What MARC tags display in Mango?
A: Please refer to the MARC Field Mappings in Mango Document listed below:
Q: How often is Mango's data refreshed?
A: Data refresh occurs as follows:
Q: How often are the Browse indexes updated?

Q: Where is the link to the Mango Enhancements Priority List?
A: The link can be found on the UISC LibGuide and here:
